title: Supplemental material for "An open-source, stochastic, six-degrees-of-freedom rocket flight simulator, with a probabilistic trajectory analysis approach"

description: Dataset supporting the Scitech 2017 conference paper.

Predicting the flight-path of an unguided rocket can help overcome unnecessary risks. Avoiding residential areas or a car-park can improve the safety of launching a rocket significantly. Furthermore, an accurate landing site prediction facilitates recovery.

This paper introduces a six-degrees-of-freedom flight simulator for small, solid-fuelled, unguided rockets. The open-source software package assists the user with the design of rockets, and its simulation core models both the rocket flight and the parachute descent in stochastic wind conditions.

Furthermore, the uncertainty in the input variables propagates through the model via a Monte-Carlo wrapper, simulating a range of possible flight conditions.

The resulting trajectories are captured as a Gaussian process, which assists in the statistical assessment of the flight conditions in the face of uncertainties, such as changes in wind conditions, failure to deploy the parachute, and variations in thrust.

This approach also facilitates concise presentation of such uncertainties via visualisation of trajectory ensembles.

title: Optimized air-to-refrigerant heat exchanger with low-GWP refrigerants.

description: This paper presents an analytical evaluation of the performance of low-GWP refrigerants in a finned-tube evaporator used for residential cooling applications. The study employed an evolutionary-computation optimization module to examine the effect of a refrigerant circuitry design on performance of twelve alternative refrigerants for R22 and R410A. The study showed that high-pressure fluids benefited most from refrigerant circuitry optimization, with R744 achieving a capacity increase of over 13 %. Among lower-pressure fluids, the capacity of an R717 evaporator increased by over 10 %. The effect of optimized refrigerant circuitries on the system performance was estimated. The results show that zeotropic blends with a large temperature glide are particularly sensitive to the refrigerant circuitry and may suffer significant performance degradation in heat exchangers with improper design.

title: Experimental investigation of Marangoni convection and surface tension of aqueous lithium bromide solutions with additives at low pressure.

description: Optimization of absorption chillers is a fundamental task to pursue in the refrigeration industry, since these chillers are still characterized by large sizes and low efficiency. An efficient way to achieve this aim is by the mean of alcoholic surfactants. Indeed, when added to the working fluid pair (waterlithium bromide) in small quantities, they lower the surface tension and induce a local Marangoni convection at the liquid/vapor interface. As a consequence of the better wetting of the tubes, the heat and mass transfer in the absorber is increased. Nevertheless, values of surface tension measured in literature tend to scatter and the influence of many factors on the enhancement mechanism is not yet fully understood. Surface tension of water and aqueous lithium-bromide solution with different surfactants is experimentally investigated. 1-octanol and 2-ethylhexanol are used as additives. Their concentration in the solution is varied in a wide range. Surface tension is measured by the pendant drop method. Among the two additives investigated, 1-octanol leads to the smallest values of surface tension. Highest reduction of surface tension is observed when the additive is delivered to the surface through vapor phase. Based on results obtained, a new experimental setup for measurements at low pressure is developed and first surface tension measurements at low pressure are presented.

title: Practical tests with R290 used in reefer container refrigeration leakage testing.

description: The option of using flammable refrigerants in the reefer container has already been studied and reported by König (2013, 2014) in various publications. In the present paper, the results of experiments are presented, related to the investigation of the potential fire and explosions risks by R290 leaks in refrigerated containers. A safety concept for reefer containers operating with R290 as refrigerant has been tested and validated. In addition, there were extensive leakage simulations, the results have been evaluated for the comparison with the practical tests. Both experiments and the simulations were done at the Federal Institute for Materials Research and Testing (BAM). Further tests are carried out by the manufacturer with the support of the firefighting service and the Danish institute of Fire and Security Technology (DBI). The results from practical tests and the leakage simulations allow for first generalization and more precise studies with respect to potential risks of refrigerant leaks. Potentially explosive atmospheres situations can be evaluated much easier and appropriate measures can be derived. It turns out that dangerous situations for small, medium and rupture of pipe leaks are manageable. The results of the practical testing of leaking R290 inside and outside of a reefer container showed that the risk is being commonly overestimated.

title: Comparison of the energy consumption of ground-source and air-to-water propane heat pumps for the heating needs around Europe.

description: The most widely used refrigerants for heat pump applications in Europe are HFCs. These refrigerants have a significant direct contribution to global warming. For this reason, they are being phased-out, as established by the so-called F-gas Regulation (EU Reg. 517/2014). Propane is among the possible substitutes for heat pumps used for space heating and cooling. This work aims to evaluate the potential of propane heat pumps focusing on the type of source of energy adopted: ground and air. A ground coupled water-to-water and an air-to-water heat pumps were modeled and their performance parameters were correlated as a function of the boundary conditions at both the evaporator and the condenser. Different climates typical of average, warm and cold regions of Europe were investigated. For each of these regions, a user type was identified and a heating demand profile was used, also taking into account the characteristics of the existing building stock. In order to assess the units, an integrated model of the system was developed in TRNSYS including the heat pump, the climatic conditions, the controls and the thermal load. Results obtained led to the conclusion that energy saving can be achieved by exploiting different technologies depending on the type of user and on the climate taken into account.

title: Supermarket application. CO2 all-in-one transcritical energy pack for HVAC&R integration in small store. Data analysis.

description: Today the trend for buildings in EU is getting closer to the n-ZEB (nearly - Zero Energy Building). This means that refrigeration is becoming, year after year, one of the most important and one of the last thermal loads in food retail shops. Refrigeration systems are most usually standalone systems that sometimes have secondary connections to other systems. These connections consist, in most cases, of passive heat recovery based on heat exchangers. This paper presents the results of an energy pack consisting of an all-in-one R744 trans-critical device for supermarket application actively producing on demand thermal power for heating, cooling and refrigeration. The energy pack consists of an R744 transcritical system able to modify independently three pressure levels in order to satisfy the whole thermal demand of the store. The aim of the study is to understand how much the all-in-one solution helps to achieve the efficient use of R744 for refrigeration in a small format food store. This paper analyzes a collection of data coming from a real store installed in UK. The results of the analysis are coupling with the results obtained with a full-size prototype running in a facility laboratory, in order to extend the analysis with different combinations of temperature, power and load displacement.

title: Numerical modeling of the off-design performance of a transcritical CO2 two-phase ejector cycle.

description: Ejector assisted cycles are known to offer significant COP and capacity improvements, especially for transcritical CO2 systems, when operated at the ejector design conditions. However, significant deviation from design conditions can lead to poor ejector and cycle performance. In this paper, a numerical model of a transcritical CO2 ejector cycle accounting for off-design ejector performance is developed. Experimental data from a CO2 ejector cycle, taken over a range of compressor speeds and ambient temperatures, is used to develop empirical models for the ejector and compressor. The evaporator in the system is a counterflow, microchannel heat exchanger and is simulated using a finite difference model capable of accounting for the heat transfer and pressure drop throughout the heat exchanger. The models of the individual components and cycle are validated using experimental data; good agreement between model and experiment is obtained.

title: Experimental comparison of the performance of a CO2 ejector cycle for transcritical and subcritical operation.

description: The use of a two-phase ejector to improve the COP and capacity of CO2 vapor compression systems has been a topic of much research in recent years. Studies often investigate the performance of the CO2 ejector cycle when operated in transcritical mode, focusing on controlling and optimizing high-side pressure. However, less focus is given to subcritical operation of CO2 ejector cycles as well as how well the same ejector and system can operate in both modes. This paper presents the results of an experimental investigation of a CO2 ejector cycle over a range of ambient temperatures, allowing the system to operate in both transcritical and subcritical modes. An adjustable ejector using a needle to control nozzle throat size, often used in CO2 ejector studies, is used to control high-side pressure and improve COP for transcritical mode. It is observed that the adjustable ejector can be used to control and optimize the performance of the system for subcritical operation as well with a similar control concept as used for transcritical operation.

title: Experimental study on control methods for transcritical CO2 two-phase ejector systems at offdesign conditions.

description: Recent studies have shown that expansion work recovery by use of a two-phase ejector offers significant opportunity for improving the COP of refrigeration systems, especially transcritical CO2 systems. However, performance improvement is known to be less significant at off-design conditions that are not as favorable to the ejector cycle. This paper investigates methods for controlling the high-side pressure of a transcritical CO2 ejector cycle. The use of an ejector with an adjustable motive nozzle throat area as well as a simple expansion valve upstream of the ejector to actively control high-side pressure are investigated and compared experimentally. Proper control of evaporator flow rate for different conditions is also investigated, and the penalty for not actively controlling the evaporator metering valve is also investigated. The control methods are investigated over a range of capacities and ambient temperatures in order to see the performance penalties to a transcritical CO2 ejector cycle when it is not controlled properly.

title: Analysis of cold thermal energy storage concepts in CO2 refrigeration systems.

description: The environmentally friendly refrigerant CO2 becomes more and more popular and is widely used for different applications, such as heat pumps or refrigeration systems, especially in commercial refrigeration. Options to increase efficiency of CO2 refrigeration systems, also under unfavourable boundary conditions as high ambient temperatures, are available. However, these options, as for instance ejectors or parallel compressors, can only increase efficiency in certain operation points. Depending on the boundary conditions, the overall system performance can be affected by the operation in part load. Cold Thermal Energy Storages (CTES) can shift the energy consumption in time and thus help to avoid inefficient part load operation of the refrigeration system. This can potentially lead to a higher overall efficiency of the system. Being able to shift the energy consumption to periods of lower electricity prices can further reduce energy costs. Additionally, they can be used to reduce electrical peak consumption and thus enable the integration of refrigeration systems in smart grids. Furthermore, the downsizing of certain equipment, as for instance compressors, can be an advantage of CTES. There are many kinds of CTES, which can be categorized regarding their size, their working principle (sensible/latent) and integration (central/decentral) into the refrigeration system. This paper describes and analyses various CTES concepts for CO2 refrigeration systems. The performance of the concepts will be assessed via thermodynamic analysis for different boundary conditions. Furthermore, the advantages and shortcomings from a practical point of view will be discussed.

title: National Surveys on Energy and Environment [United States]

description: The National Surveys on Energy and Environment (NSEE), a core activity in CLOSUP's Energy and Environmental Policy Initiative, reflects a formal partnership between the Muhlenberg Institute of Public Opinion at Muhlenberg College and the Center for Local, State, and Urban Policy at the University of Michigan's Gerald R. Ford School of Public Policy. NSEE surveys include twice per year national opinion surveys on issues directly related to climate change and energy policy, as well as other surveys conducted on a range of topics such as hydraulic fracturing ("fracking"), the Great Lakes, and wider issues of energy and environment. NSEE is co-directed by professor Barry Rabe at the University of Michigan, and professor Christopher Borick at Muhlenberg College. For more information on the collaboration between the University of Michigan and Muhlenberg College, please see the recent article from Muhlenberg Magazine. For more information about the NSEE, contact CLOSUP staff at 734-647-4091 or closup@umich.edu. From 2008-2012 the survey was called the “National Survey of American Public Opinion on Climate Change” (NSAPOOC); starting in 2013 the survey was renamed to the “National Surveys on Energy and Environment” (NSEE). <br><br>The NSEE is committed to transparency in all facets of our work, including timely release and posting of data from each survey wave. A grant from the Office of the Provost at the University of Michigan will enable us to expand and accelerate this work, including providing online access to NSEE frequency tables and survey instruments, followed by datasets. Users can see a list of topics covered by the NSEE, and search for questions by text, variable name, or variable category on CLOSUP's website. <br><br>Although the datasets are listed by survey wave, the NSEE is a valuable source of longitudinal public-opinion data on climate change and energy policy. Many questions have been asked over multiple waves, including questions about belief in global warming that have been asked in every wave of the NSEE. Consult the NSEE Crosswalk to see which questions have been asked in prior and subsequent waves of the NSEE. To facilitate longitudinal analysis, the NSEE datasets use a longitudinal variable naming scheme to facilitate longitudinal analysis. Variable names include two parts: a subject category for the question, and a description of the contents of the question. When a question has been asked with the same text and response options over multiple waves, the same variable name will be used in each dataset. For more information on the longitudinal naming scheme users should consult the codebooks for the datasets. <br><br><br>
