Experimental Investigation of Heat Transfer and Pressure Drop of Pipes with Internal Roughness
Creators: Raoufi, Abdolreza
Publisher: name: University of Alberta Library
Year: 2022

In many industrial heat exchangers, it is desirable to improve the rate of heat transfer from a pipe wall to the fluid flow. This improvement is commonly made by adding some form of roughness to the pipe surface. However, the added roughness often leads to an increase in the pressure drop of the flow. The objective of this study is to experimentally compare the rate of heat transfer enhancement and friction factor for fully developed turbulent pipe flows with different roughness elements.

The experiments were conducted on a smooth pipe and four pipes with different internal roughness elements manufactured using steel mesh and ball bearings. The nominal diameter of all pipes was two inches. The working fluid was air, and the flow properties were measured at Reynolds numbers of 20,000 to 90,000 in increments of 10,000 under a constant pipe wall temperature of 375℃. The Nusselt number and friction factor of the rough pipes were evaluated, and the results were compared to the smooth pipe. It was found that Nusselt number of the pipes with mesh-type roughness increases by approximately 5%, while the Nusselt number of the pipes with roughness elements made from ball-bearings increased by 23 to 33%. The increase of friction factor was 66% for the pipes covered with mesh and 33 to 43% for pipes with ball bearings. The experimental results indicate that adding ball bearings to the internal surface of the pipe can lead to a significant improvement in the rate of heat-transfer. Adding a mesh-type roughness to the pipes can have marginal improvements in heat transfer and a large increase in frictional losses, and therefore it is not recommended.

description: The second generation Low Resolution Spectrograph (LRS2) is a new facility instrument for the Hobby-Eberly Telescope (HET). Based on the design of the Visible Integral-field Replicable Unit Spectrograph (VIRUS), which is the new flagship instrument for carrying out the HET Dark Energy Experiment (HETDEX), LRS2 provides integral field spectroscopy for a seeing-limited field of 12 x 6 arcseconds. For LRS2, the replicable design of VIRUS has been leveraged to gain broad wavelength coverage from 370 nm to 1 micron, spread between two fiber-fed dual-channel spectrographs, each of which can operate as an independent instrument. The blue spectrograph, LRS2-B, covers 370-470 nm and 460-700 nm at fixed resolving powers of ~1900 and ~1100, respectively, while the red spectrograph, LRS2-R, covers 650-842 nm and 818-1050 nm with both of its channels having a resolving power of ~1800. In this paper, we present a detailed description of the instrument's design in which we focus on the departures from the basic VIRUS framework. The primary modifications include the fore-optics that are used to feed the fiber integral field units at unity fill-factor, the cameras' correcting optics and detectors, and the volume phase holographic grisms. We also present a model of the instrument's sensitivity and a description of specific science cases that have driven the design of LRS2, including systematically studying the spatially resolved properties of extended Lyman-alpha blobs at 2 < z < 3. LRS2 will provide a powerful spectroscopic follow-up platform for large surveys such as HETDEX.

description:  Abstract Solar surface magnetic field evolution plays a dominant role in the variability of Total Solar Irradiance (TSI) modulating the appearance of various features (e.g., sunspots, faculae, network, etc.) on the solar surface. Different proxies of magnetic activity have been introduced to study or correlate solar variability and TSI. In this work, we present a couple of solar surface magnetic flux indices: the daily strong field density (SFD) and weak field density (WFD), which
 are calculated from SDO/HMI. These are defined on the basis of a suitable magnetic threshold and can be associated with solar active regions that we assume to be related to short (daily) and long (solar rotation) time scales. In the analysis, we used TSI data from the radiometers of the VIRGO of the SOHO Mission. More in detail, we present the characterization of the influence of the magnetic field flux variation, described by SFD and WFD proxies, on the TSI using the Pearson correlation and wavelet analysis. The Pearson correlation shows that SFD is negatively correlated with TSI, with a strong correlation coefficient of -0.85, while WFD is not correlated. The bootstrapping tests also confirm
 that the influence of SFD on TSI is more significant than that of WFD. Finally, the wavelet analysis between SFD and TSI supports the idea that the SFD and TSI have a causality linkage at the solar rotational time scale, while the same analysis indicates that the SFD dominantly influences the TSI variability in the rotational time
 scale.

THREE-DIMENSIONAL OUTCROP MODELLING, SEDIMENTOLOGY, AND ICHNOLOGY OF THE FALHER D MEMBER, NORTHEAST BRITISH COLUMBIA, CANADA
Creators: Acikelli, Arzu
Publisher: name: University of Alberta Library
Year: 2022

The Lower Cretaceous Falher Member is an important hydrocarbon reservoir in the Deep

Basin of Alberta and British Columbia. Owing to its economic importance, it has been the subject

of many studies. However, there remains contention on the depositional interpretation of

individual Falher Member conglomerate units. Both shoreface and wave-dominated deltaic

models have been proposed. As such, the Falher Member is an ideal outcrop analog that can be

used to assess the spatial distribution of component lithofacies and sedimentary features of

shoreface and wave-dominated delta deposits.

The present research uses sedimentology and ichnology, within the context of 3D

photogrammetric models, of several Falher-equivalent outcrop successions on Mount Spieker in

northeastern British Columbia. Facies distributions and relationships are assessed through 3D

outcrop models and collected field data. The presence of fluid mud lenses, terrestrial fossil

fragments, and impoverished suites of trace fossils confirm that the study interval was deposited

proximal to a fluvial sediment source. The abundance of HCS sandstone units and pebbly storm

lags indicates robust storm-wave reworking at the time of deposition. The along-strike

heterogeneity in facies distribution is interpreted as evidence for delta asymmetry. The proposed

depositional model suggests that strong longshore currents were the main reason for delta

asymmetry. In this wave-dominated deltaic setting, the updrift side presents better reservoir

targets including thick, clast-supported conglomerate units. The downdrift side consists of finer

grained argillaceous deposits representing poorer reservoir quality. This study documents the

sedimentology of the studied outcrops and discusses the depositional processes causing the

heterogeneity in facies type and distribution in a wave-dominated, gravel-dominated delta setting.

In the stationary creep regime we have determined the exponents of the shear rate dependence of the shear stress and defect density, being $α= 1.15 \pm 0.1$ and $β= 2.4 \pm 0.4$, respectively. We show that the formation and rapid glide motion of dislocation pairs in the lattice are dominant processes.

Constraining Hydrodynamics on Plesiosaur Locomotion
Creators: Pourfarzan, Ali
Publisher: name: University of Alberta Library
Year: 2022

Plesiosaurs were a diverse group of Mesozoic marine reptiles, notable among both extinct and extant animals for their unique body planform. Despite being known for more than 300 years, many aspects of their locomotion and behavior remain as mystery. Unlike any other flapping species, plesiosaurs exhibit two pairs of near-identical wing-like flippers, which have remained consistent throughout their evolution. Despite the similarity in geometry between fore and hind flippers, their morphologies have been identified to be slightly different. This has given rise to contradicting hypotheses on locomotion and their behavior. In particular, the role of the hind flipper and the relative motion of the flippers have been questioned. In this thesis, which consists of two research chapters, two different approach are considered

to address these questions. First, by using universal scaling laws, it is shown that the group of plesiosaurs with short necks and large heads, known as pliosauroids, likely had a high agility level, possibly similar to penguins, while long-necked, small-headed plesiosaurs (plesiosauroids) likely had limited agility, possibly similar to that observed in sea turtles. Second, through a series of particle image velocimetry experiments on the effect of varying amplitude ratio on tandem oscillating foils, it is demonstrated that plesiosaurs utilizing rear-biased and equal amplitude propulsion, could have achieved higher thrust production and propulsive efficiency. However, the rear-biased model is found to be more efficient with slightly higher thrust production. This strategy may have been utilized by pliosauroids, known to be pursuit predators, as it is consistent with fossil records, with joints of the hind flipper accommodating greater flapping angles. It is possible that this strategy was also used by plesiosauroids for high thrust production such as during escape, however it is inconsistent

with fossil measurements. The findings of this work suggest that amplitude ratio, along with other important parameters such as varying the phase differential of flipper oscillation and

inter-foil spacing, was a critical optimizing parameter for the propulsive performance of a tandem-flipper propulsor.

description: We investigate the surface spot activity of the rapidly rotating, lithium-rich active single K-giant DI Psc to measure the surface differential rotation and understand the mechanisms behind the Li-enrichment. Doppler imaging was applied to recover the surface temperature distribution of DI Psc in two subsequent rotational cycles using the individual mapping lines Ca I 6439, Fe I 6430, Fe I 6421 and Li I 6708. Surface differential rotation was derived by cross-correlation of the subsequent maps. Difference maps are produced to study the uniformity of Li-enrichment on the surface. These maps are compared with the rotational modulation of the Li I 6708 line equivalent width. Doppler images obtained for the Ca and Fe mapping lines agree well and reveal strong polar spottedness, as well as cool features at lower latitudes. Cross-correlating the consecutive maps yields antisolar differential rotation with shear coefficient -0.083 +- 0.021. The difference of the average and the Li maps indicates that the lithium abundance is non-activity related. There is also a significant rotational modulation of the Li equivalent width.

description: Today the availability of high mobility graphene up to room temperature makes ballistic transport in nanodevices achievable. In particular, p-n-p transistor in the ballistic regime gives access to the Klein tunneling physics and allows the realization of devices exploiting the optics-like behavior of Dirac Fermions (DF) as in the Vesalego lens or the Fabry Pérot cavity. Here we propose a Klein tunneling transistor based on geometrical optics of DF. We consider the case of a prismatic active region delimited by a triangular gate, where total internal reflection may occur, which leads to the tunable suppression of the transistor transmission. We calculate the transmission and the current by means of scattering theory and the finite bias properties using Non Equilibrium Green's Function(NEGF) simulation.

description: L’agriculture est l’un des principaux secteurs émetteurs de gaz à effets de serre (GES), en étant la principale source de méthane (CH4) et de protoxyde d’azote (N2O), deux importants GES autres que le CO2. Réciproquement, le climat est un facteur important dans les systèmes de production agricole. Le changement climatique affectera les rendements agricoles et exercera une pression supplémentaire sur le fonctionnement des écosystèmes, avec des conséquences potentiellement importantes sur la sécurité alimentaire, la vulnérabilité des ménages ruraux et la biodiversité. Dans nos travaux, nous approfondissons la compréhension du rôle de la discipline économique sur le changement climatique à partir d’une analyse systématique de la littérature sur le sujet. Puis nous utilisons des approches analytiques permettant d’éclairer ce que pourrait être une politique climatique dans le secteur agricole et comment les marges d’adaptation sont conditionnées par, et interagissent avec, les déterminants économiques.
Partial wave series expansions in spherical coordinates for the acoustic field of vortex beams generated from a finite circular aperture

description: Stemming from the Rayleigh-Sommerfeld surface integral, the addition theorems for the spherical wave and Legendre functions, and a weighing function describing the behavior of the radial component of the normal velocity at the surface of a finite circular radiating source, partial-wave series expansions are derived for the incident field of acoustic spiraling (vortex) beams in a spherical coordinate system centered on the axis of wave propagation. Examples for vortex beams, comprising ρ-vortex, zeroth-order and higher-order Bessel-Gauss and Bessel, truncated Neumann-Gauss and Hankel-Gauss, Laguerre-Gauss, and other Gaussian-type vortex beams are considered. The mathematical expressions are exact solutions of the Helmholtz equation. The results presented here are particularly useful to accurately evaluate analytically and compute numerically the acoustic scattering and other mechanical effects of finite vortex beams, such as the axial and 3D acoustic radiation force and torque components on a sphere of any (isotropic, anisotropic etc.) material (fluid, elastic, viscoelastic etc.). Numerical predictions allow optimal design of parameters in applications including but not limited to acoustical tweezers, acousto-fluidics, beam-forming design and imaging to name a few.

description: Bosons interacting repulsively on a lattice with a flat lowest band energy dispersion may, at sufficiently small filling factors, enter into a Wigner-crystal-like phase. This phase is a consequence of the dispersionless nature of the system, which in turn implies the occurrence of single-particle localised eigenstates. We investigate one of these systems - the sawtooth lattice - filled with strongly repulsive bosons at filling factors infinitesimally above the critical point where the crystal phase is no longer the ground state. We find, the the hard-core limit, that the crystal retains its structure in all but one of its cells, where it is broken. The broken cell corresponds to an exotic kind of repulsively bound state, which becomes delocalised. We investigate the excitation spectrum of the system analytically and find that the bound state behaves as a single particle hopping on an effective lattice with reduced periodicity, and is therefore gapless. Thus, the addition of a single particle to a flat-banded system at critical filling is found to be enough to make kinetic behaviour manifest.

description: This contribution presents experimental study of two-dimensional pedestrian flow with the aim to capture the pedestrian behaviour within the cluster formed in front of the bottleneck. Two experiments of passing through a room with one entrance and one exit were arranged according to phase transition study in Ezaki et al. (2012), the inflow rate was regulated to obtain different walking modes. By means of automatic image processing, pedestrians' paths are extracted from camera records to get actual velocity and local density. Macroscopic information is extracted by means of virtual detector and leaving times of pedestrians. The pedestrian's behaviour is evaluated by means of density and velocity. Different approaches of measurement are compared using several fundamental diagrams. Two phases of crowd behaviour have been recognized and the phase transition was described.

description: Dans ces travaux, nous examinons les arbitrages entre recyclage et extraction, de façon générique puis dans deux cas appliqués, la pâte à papier et les batteries de véhicules électriques. À cette fin, sont combinées des approches théoriques de l’économie des ressources ainsi que des approches de simulation et de prospective utilisant des données calibrées. Les résultats montrent que quand on s’intéresse à l’économie du recyclage, il est nécessaire de prendre en compte les différentes externalités liées à l’extraction, la transformation et la consommation de ressources. Cela inclut l’épuisement des stocks naturels, les impacts environnementaux de l’accumulation des déchets et les émissions de gaz à effet de serre.

description: We investigate ballistic vibrational energy transport through optical phonon band in oligomeric chains in the presence of decoherence. An exact solution is obtained for the excitation density in the space-time representation in the continuous limit and this solution is used to characterize the energy transport time and intensity. Three transport mechanisms are identified such as ballistic, diffusive and directed diffusive regimes, occurring at different distances and time ranges. The crossover between the two diffusive regimes is continuous, while the switch between the ballistic and diffusive mechanisms occurs in discontinuous manner in accord with the recent experimental data on energy transport in perfluoroalkanes.

description: The transition between low and high density phases is a typical feature of systems with social interactions. This contribution focuses on simple evacuation design of one room with one entrance and one exit; four passing-through experiments were organized and evaluated by means of automatic image processing. The phase of the system, determined by travel time and occupancy, is evaluated with respect to the inflow, a controlled boundary condition. Critical values of inflow and outflow were described with respect to the transition from low density to congested state. Moreover, microscopic analysis of travel time is provided.

description: The effect of the isospin/charge asymmetry and an external magnetic field in the location of the critical end point (CEP) in the QCD phase diagram is investigated. By using the 2+1 flavor Nambu--Jona-Lasinio model with Polyakov loop (PNJL), it is shown that the isospin asymmetry shifts the CEP to larger baryonic chemical potentials and smaller temperatures, and in the presence of a large enough isospin asymmetry the CEP disappears. Nevertheless, a sufficiently high external magnetic field can drive the system into a first order phase transition again.
