Different types of CAES systems are classified based on their thermal management: Adiabatic, Diabetic, or Isothermal. During gas expansion, the temperature of the gas drops to sub-zero degrees Celsius, which must be increased to match the operating conditions of the air motor and improve system efficiency. To address this issue, a cold thermal energy storage system is proposed in this study. The system takes advantage of the temperature drop effect by rejecting heat into a phase change material heat exchanger. The resulting cooling effect can be used to improve the efficiency of both the CAES and a refrigeration system. To evaluate the performance of the CAES system, a micro-scale setup was built and studied both analytically and experimentally. A second small setup was constructed and studied from the perspective of the operating gas and the heat exchanging medium, which was water. Due to the limited storage capacity, the operation time was short, but the results demonstrated that the system was viable. A third setup was built to test the mechanical performance of different air turbine sizes and gear ratios. A computational fluid dynamics (CFD) model of the heat exchanger was developed using ANSYS and verified using experimental results. This model was used to study and design the proposed unit’s design, which was then built and tested experimentally. To avoid complexity, some parameters were derived from initial experimental results. The final experiment made use of three consecutive expansion stages, with a phase change material absorbing the coolness of the fluid flow. A water-cooling cycle was introduced to make use of the stored coolness and assess the energy savings compared to a conventional refrigeration system. The integration of the designed unit was successful and resulted in an increase in the efficiency of the CAES from 31.4% to 39.45%. In summary, this study proposes a cold thermal energy storage system that improves the efficiency of the CAES and a refrigeration system, and the experimental results demonstrate the viability of this system.College of EngineeringDepartment of Mechanical EngineeringMaster of Science in Mechanical Engineering (MSME)Orhan, Mehmet FatihAl Alami, Abdul Hai2023-09-04T10:17:56Z2023-09-04T10:17:56Z2023-05info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisapplication/pdf35.232-2023.30http://hdl.handle.net/11073/25332en_USoai:repository.aus.edu:11073/253322026-06-11T06:36:21Z |
