Available in PDF, EPUB and Kindle. Book excerpt: Faced with an ever-growing resource scarcity and environmental regulations, the last 30 years have witnessed the rapid development of various renewable power sources, such as wind, tidal, and solar power generation. The variable and uncertain nature of these resources is well-known, while the utilization of power electronic converters presents new challenges for the stability of the power grid. Consequently, various control and operational strategies have been proposed and implemented by the industry and research community, with a growing requirement for flexibility and load regulation placed on conventional thermal power generation. Against this background, the modelling and control of conventional thermal engines, such as those based on diesel and gasoline, are experiencing serious obstacles when facing increasing environmental concerns. Efficient control that can fulfill the requirements of high efficiency, low pollution, and long durability is an emerging requirement. The modelling, simulation, and control of thermal energy systems are key to providing innovative and effective solutions. Through applying detailed dynamic modelling, a thorough understanding of the thermal conversion mechanism(s) can be achieved, based on which advanced control strategies can be designed to improve the performance of the thermal energy system, both in economic and environmental terms. Simulation studies and test beds are also of great significance for these research activities prior to proceeding to field tests. This Special Issue will contribute a practical and comprehensive forum for exchanging novel research ideas or empirical practices that bridge the modelling, simulation, and control of thermal energy systems. Papers that analyze particular aspects of thermal energy systems, involving, for example, conventional power plants, innovative thermal power generation, various thermal engines, thermal energy storage, and fundamental heat transfer management, on the basis of one or more of the following topics, are invited in this Special Issue: • Power plant modelling, simulation, and control; • Thermal engines; • Thermal energy control in building energy systems; • Combined heat and power (CHP) generation; • Thermal energy storage systems; • Improving thermal comfort technologies; • Optimization of complex thermal systems; • Modelling and control of thermal networks; • Thermal management of fuel cell systems; • Thermal control of solar utilization; • Heat pump control; • Heat exchanger control.

This book was released on 2015-01-26 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Building energy design is currently going through a period of major changes. One key factor of this is the adoption of net-zero energy as a long term goal for new buildings in most developed countries. To achieve this goal a lot of research is needed to accumulate knowledge and to utilize it in practical applications. In this book, accomplished international experts present advanced modeling techniques as well as in-depth case studies in order to aid designers in optimally using simulation tools for net-zero energy building design. The strategies and technologies discussed in this book are, however, also applicable for the design of energy-plus buildings. This book was facilitated by International Energy Agency's Solar Heating and Cooling (SHC) Programs and the Energy in Buildings and Communities (EBC) Programs through the joint SHC Task 40/EBC Annex 52: Towards Net Zero Energy Solar Buildings R&D collaboration. After presenting the fundamental concepts, design strategies, and technologies required to achieve net-zero energy in buildings, the book discusses different design processes and tools to support the design of net-zero energy buildings (NZEBs). A substantial chapter reports on four diverse NZEBs that have been operating for at least two years. These case studies are extremely high quality because they all have high resolution measured data and the authors were intimately involved in all of them from conception to operating. By comparing the projections made using the respective design tools with the actual performance data, successful (and unsuccessful) design techniques and processes, design and simulation tools, and technologies are identified. Written by both academics and practitioners (building designers) and by North Americans as well as Europeans, this book provides a very broad perspective. It includes a detailed description of design processes and a list of appropriate tools for each design phase, plus methods for parametric analysis and mathematical optimization. It is a guideline for building designers that draws from both the profound theoretical background and the vast practical experience of the authors.

This book was released on 2022 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among various types of solar collectors, evacuated tube solar collector (ETC) has attracted much attention, especially for their application in solar water heating systems (SWHs). However, due to the intermittency in solar intensity, the ETCs may not work at their maximum functionality. In this study, the computational fluid dynamics (CFD) modeling of a heat pipe ETC (HPETC) with and without the integration of phase change materials (PCMs) is performed. In order to cross-validate the obtained results from CFD and recent experimental analysis, the boundary conditions are set as the field-testing data. The simulation results show an acceptable agreement with the experimental data with an average deviation of 4.8%. In order to further increase the accuracy of a numerical model, the volume of fluid (VOF) approach is adopted to simulate two-phase (evaporation-condensation process) phenomena inside a heat pipe. The result showed a 0.78% increase in numerical model accuracy when the heat pipe is simulated as a two-phase device in comparison with the simplified approach (in which HP is considered a high thermal conductive device). The result of this study showed improvement in numerical model accuracy when the VOF model is adopted. However, the VOF approach is found very time-consuming. As a result, a simplified numerical approach is adopted to optimize the thermal performance of an HPETC system. The performance of an HPETC is optimized by investigating the effect of HP position and various energy storage materials in both normal and on-demand operations. The results show that the solid-to-liquid phase change process was expedited by 48 minutes when the HP shifted from the top to the center of the glass tube. On the other hand, during normal operation, the maximum liquid fraction of PCM reached up to 98% in an optimized system whereas the conventional system reached up to only 74%. During normal operation, It is observed that the HPETC system integrated with PCM struggled to reach a melting fraction of 100% due to its poor thermal conductivity. The issue of poor thermal conductivity is addressed by impregnation of high thermal conductive porous metal to the PCM. To demonstrate the viability of the proposed approach, experimental analysis is carried out. The proposed system has reported maximum thermal efficiency of 71.71% while the conventional system showed maximum thermal efficiency of only 29.14%. Impregnation of porous metal to the PCM showed promising results and improved thermal performance in the HPETC system. The same approach is used to improve the electrical and thermal performance of a photovoltaic-thermal (PVT) system. CFD analysis is performed to assess the effect of integrating PCM + Cu porous metal with the PVT system. In addition, during the simulation, a real-time transient solar radiation boundary condition is applied to accurately predict the performance parameters such as the surface temperature of the PV cell, melting fraction of PCM, and the thermal energy stored by the system. The PVT system integrated with PCM + Cu porous metal system exhibited electrical efficiency of 11.49% which is 12.09% higher compared with the PVT system integrated with pure PCM. In addition, PV cell temperature is also decreased by 23.03 oC for the PVT system integrated with PCM + Cu porous metal. The outcome of this study can be a benchmark for further optimization of thermal energy storage-based solar collectors.

This book was released on 2021 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: Space heating is required in almost every dwelling across the country for different periods of time. The thermal energy needed to meet a heating demand can be supplied using different conventional and/or renewable technologies. Solar energy is one example of a renewable resource that can be used for supplying heating needs. It can be utilized either by using photovoltaic panels to generate electricity, that in turn can be used to operate heaters, or by using solar thermal panels. Solar thermal panels obtain higher operating efficiencies than photovoltaic panels, but solar energy for heating purposes suffers from a mismatch between supply and demand. This problem can be solved by employing large tanks that serve as seasonal thermal energy storage units. This work focuses on assessing the performance of solar thermal panels in supplying the space heating needs of a single-family dwelling in two different cities in the United States. These panels are coupled to a cylindrical tank buried in the ground for seasonal and daily energy storage, and a heat exchanger to transfer heat to the home. Storage tank size, collector area, and the working fluid mass flow rate are investigated to determine adequate values for these parameters to enhance the overall system performance. In addition, the simulation timestep for the program and the spatial grid sizes used in the CFD (computational fluid dynamics simulation) model of the storage unit have been examined to determine values of each to keep the simulation time reasonable without substantial loss in accuracy. These results are obtained by mathematically modeling the system components, the solar thermal panels, the heat exchanger, and the storage tank; then programming this mathematical model in MATLAB. Parts of the developed computer code were obtained from previous work and have been modified to suit the purpose of this project. Flat plate solar panels have been chosen for use as the solar collectors. An unmixed, crossflow heat exchanger is considered for transferring the thermal energy from the glycol-water mixture in the collectors to the air in the house. The storage unit CFD simulation is composed of the tank, insulation, and ground surrounding the tank and is based on the SIMPLE algorithm developed by Patankar.
