Design and Analysis of Cooling Systems for Combustion Chambers in Turbine Engines: A Comparison of Oil and Gas Cooling Fluids

This study focuses on the design and analysis of a cooling system for a combustion chamber in a turbine engine. The objective is to compare the cooling performance of oil and gas as cooling fluids using CAD modeling in CATIA and computational fluid dynamics (CFD) simulations in ANSYS Fluent. The design requirements, including cooling rate, pressure drop, temperature requirements, fluid properties, material compatibility, and environmental impact, were defined and incorporated into the CAD model. The CFD simulations were conducted to evaluate the temperature distribution and pressure dynamics within the combustor chamber. The results provided insights into the advantages and drawbacks of using oil and gas as cooling fluids, considering factors such as heat absorption, thermal conductivity, viscosity, pressure drop, and power consumption. Material compatibility and environmental considerations were also addressed. The findings offer a foundation for informed decision-making regarding the selection of the most suitable cooling fluid. However, real-world testing is recommended to validate the simulation results and ensure the chosen cooling fluid meets the design requirements effectively and efficiently. By combining computational simulation and physical testing, this study contributes to the design of efficient and durable cooling systems for gas turbine engines.
