Simulating Traffic-wake Effects in a Wind Tunnel
Authors: McAuliffe Brian , Barber Hali
Published: April 2023

Road-vehicle platooning is known to reduced aerodynamic drag. Recent aerodynamic-platooning investigations have suggested that follower-vehicle drag-reduction benefits persist to large, safe inter-vehicle driving distances experienced in everyday traffic. To investigate these traffic-wake effects, a wind-tunnel wake-generator system was designed and used for aerodynamic-performance testing with light-duty-vehicle (LDV) and heavy-duty-vehicle (HDV) models. This paper summarizes the development of this Road Traffic and Turbulence System (RT2S), including the identification of typical traffic-spacing conditions, and documents initial results from its use with road-vehicle models.

Analysis of highway-traffic-volume data revealed that, in an uncongested urban-highway environment, the most-likely condition is a speed of 105 km/h with an inter-vehicle spacing of about 50 m. Probability distributions for spacing and road speed were used to identify a range of suitable inter-vehicle spacings to target for wake conditions. Combining these data with previous research activities that examined the characteristics of road-vehicle wakes, three phases of development for the RT2S were undertaken in multiple wind tunnels leading to a system using porous grids and sets of vertically-oriented vanes. Specific grid and vane combinations generate wake shapes, wind-speed deficits, flow-angularities, and turbulence representative of every-day traffic wakes. Lateral positioning of the system and rotation of the vanes provide wake positioning and flow characteristics representing a variety of wake-in-crosswind conditions, while being able to effectively change the lane of the wake-source vehicles.

The results of two experiments are presented to document the influence of traffic wakes, via application of the RT2S, on the aerodynamic performance of road vehicles. First, measurements are presented based on the use of a prototype version of the system with a 15%-scale DrivAer fastback model. Drag reductions from 10% to 31% and side-force-coefficient reductions in excess of 50% were observed for the DrivAer model, relative to uniform-flow conditions, for the 13 specific wake-like conditions replicated. The second set of experiments applied the final RT2S design to testing of a 30%-scale tractor-trailer HDV model, which showed drag reductions as high as 15% for an HDV-wake configuration, with drag reductions of 2% measured for a compact-sedan-wake at 50 m effective forward distance, relative to uniform winds. For both sets of experiments, examining wake effects on LDV and HDV models, changes in aerodynamic performance are attributed in large part to reductions in effective dynamic pressure, but surface-pressure measurements indicate that flow-angularity variations also play a role in crosswind conditions.
Effects of Vehicle Numbers and Vehicle Types on Drag Reduction of Platoons with Different Front-Edge Radius

Published: April 2023

The platoon of intelligent vehicles can significantly reduce the aerodynamic drag, which has broad development prospects. This research numerically studies the effect of Reynolds number (Re = 3.32×105 to 19.94×105), the vehicle numbers (3-, 5-, 8-vehicle), and vehicle types (fastback, notchback, and squareback) on the platoon drag reduction with three different front-edge radius (R*=R/W×100 = 9.36, 4.68 and 2.34). The results show that when the Reynolds number is greater than 9.97×105, the drag coefficient ratio CD/CDi (CDi is the drag coefficient of the isolated vehicle) of each vehicle in the platoon is less affected by the Reynolds number. When R*=9.36, the averaged CD/CDi of the fastback platoon (even above 1) is higher than that of both the notchback platoon and the squareback platoon without front-edge separation at the leading vehicle due to the weakest shielding effect on the following car resulting from the prominent downwash wake. Compared with R*=9.36, when the flow separation occurs at the front-edge R*=2.34, the averaged CD/CDi of the platoon with different vehicle numbers and each vehicle (except the leading vehicle) in the platoon both exhibit a tremendous reduction. This drag reduction should be attributed to the shielding effect caused by the front-edge separation at the leading vehicle. In addition, at the front-edge R*=2.34, the averaged CD/CDi of the fastback and squareback platoon are comparable, much larger than that of the notchback platoon featured by a balanced wake and shortened recirculation flow at in-notch region. Except for the fastback platoon at R*=9.36, the other platoon's averaged CD/CDi decreases gradually with the increase of vehicle number. This work has a vital reference significance for the aerodynamic optimization design of the future intelligent vehicle platoon.
Finite Element Analyses of Macroscopic Stress-Strain Relations and Failure Modes for Tensile Tests of Additively Manufactured AlSi10Mg with Consideration of Melt Pool Microstructures and Pores
Authors: Wu Shengjia , Kim Eui Seop , Pan Jwo
Published: April 2023

Finite element (FE) analyses of macroscopic stress-strain relations and failure modes for tensile tests of additively manufactured (AM) AlSi10Mg in different loading directions with respect to the building direction are conducted with consideration of melt pool (MP) microstructures and pores. The material constitutive relations in different orientations of AM AlSi10Mg are first obtained from fitting the experimental tensile engineering stress-strain curves by conducting axisymmetric FE analyses of round bar tensile specimens. Four representative volume elements (RVEs) with MP microstructures with and without pores are identified and selected based on the micrographs of the longitudinal cross-sections of the vertical and horizontal tensile specimens. Two-dimensional plane stress elastic-plastic FE analyses of the RVEs subjected to uniaxial tension are then conducted. The true stress-plastic strain curves for MPs and melt pool boundaries (MPBs) are obtained in scale with those of the tensile tests based on the microhardness values. The simulation engineering stress-strain curves of the RVEs are in good agreement with the experimental data. The simulation results indicate that the plastic deformation is initiated at the soft MPBs and near the material defects of pores, grows along MPBs in the vertical specimens or across MPs in the horizontal specimens as the macroscopic strain increases, and finally possible fracture paths connecting the regions with large plastic strains are identified. The identified failure modes are in good agreement with those from experiments. The simulation results also indicate that the MP microstructures and pores play important roles in the failure modes and anisotropy of ductility of AM AlSi10Mg.

Decreasing Mechanical Losses in High-Speed Diesel Engines
Authors: Ha Hiep Nguyen , Cong Doan Nguyen , Quoc Quan Nguyen , Van Duong Nguyen
Published: April 2023

The most preferred method for reducing mechanical losses in internal combustion
engines (ICEs) is profiling contact surfaces, which involves forming
microreliefs on the inner surface of cylinder liners (CLs). This work presents
analytical and experimental results of the frictional power losses in the
four-stroke diesel engine with smooth and microrelief CLs. The regular
microreliefs (RMR), with a groove width of 0.4 mm, an amplitude of 1.5 mm, and a
relative frictional area of 8.6%, were formed through vibration rolling.
Experiments were conducted on both smooth and microrelief cylinders by measuring
fuel consumption at 25–100% nominal load and idle mode at a constant speed. The
results showed that compared to the engine with smooth CLs, the total frictional
power is reduced by an average of 10.8%, mechanical efficiency is increased by
4.0%, and fuel consumption is decreased by 6.4% for the engine with microrelief
cylinders. The measured frictional power dropped by 0.90 kW, which is close to
the 0.81 kW value calculated using mathematical models and Ansys software
simulation.
Artificial colorization of digitized microfilms: a preliminary study
Authors: Clérice Thibault , Pinche Ariane
Published: April 2023

A lot of available digitized manuscripts online are actually digitized microfilms, a technology dating back from the 1930s. With the progress of artificial colorization, we make the hypothesis that microfilms could be colored with these recent technologies, testing InstColorization. We train a model over an ad-hoc dataset of 18 788 color images that are artificially gray-scaled for this purpose. With promising results in terms of colorization but clear limitations due to the difference between artificially grayscaled images and "naturaly" greyscaled microfilms, we evaluate the impact of this artificial colorization on two downstream tasks using Kraken: layout analysis and text recognition. Unfortunately, the results show little to no improvements which limits the interest of artificial colorization on manuscripts in the computer vision domain.

Introduction: The purpose of this study was to assess the quality and reliability of YouTube as a source of physical therapy patient education.

Methods: The study was conducted using a scoping review design that considers the various studies that have been undertaken about YouTube video's quality and reliability in the field of physical therapy. The PRISMA Reporting protocol was used to screen out articles from databases (Medline, PubMed, Science Direct, PEDro, EBSCOhost). The Pedro scale was used to check the quality of the study while Cochrane Bias Tool was used to screen for risks of bias.

Results: A total of 29 articles were included. The publications were then classified into 21 musculoskeletal articles, 4 neurological articles, 1 cardiovascular, 1 urology article, and 2 on water treatment and frailty syndrome. Overall, 18 (62.07%) of the articles were rated as poor, 7 (24.14%) as fair, and 4 (13.79%) as excellent quality. In terms of reliability, 19 articles (65.52%) were scored as poor, 3 (10.34%) as fair, and 7 (24.14%) as highly reliable. This scoping review found that YouTube can be a beneficial tool as a primary resource for patient education; however, it lacks the accuracy of material needed to answer patient/client inquiries. The articles chosen were found to have low reliability and poor quality.

Discussion: Healthcare professionals, physical therapists, and educators can use additional peer-reviewed resources to doublecheck the integrity of the material provided and ensure that the YouTube channel's source is legitimate and trustworthy.

Published: April 2023

Many inference algorithms develop the time-domain connection of the direct by employ a Kalman filter base on a first-order (or sometimes second-order) estimate of the time-varying channel amid a norm based on link toning (CM), or on the Minimization of Asymptotic Variance (MAV). To decrease the complexity of the high-dimensional RW-KF for combined opinion of the multi-path multifaceted amplitudes, we suggest using an inferior dimensional RW-KF that estimate the compound amplitude of each path separately. We demonstrate that this amounts to a simplification of the joint multi-path Kalman increase formulation through the Woodbury’s identities. Hence, this innovative algorithm consists of a superposition of self-determining single-path single-carrier KFs, which be optimized in our earlier studies. This examination allow us to settle in the optimization to the authentic multi-path multi-carrier scenario, to afford logical formulas for the mean-square error presentation and the best tuning of the future estimator in a straight line as a function of the physical parameter of the canal (Doppler frequency, signal-to-noise-ratio, power delay profile). These logical formula are known for the first-, second-, and third-order RW models used in the KF. The future per-path KF is exposed to be as well-organized as the accurate KF (i.e., the joint multi-path KF), and outperforms the autoregressive-model-based KFs future in the literature.
