DESIGN AND DEVELOPMENT OF TURBOCHARGER BASED BRAYTON CYCLE

Abstract

This study investigated the design and development of a high-efficiency Brayton cycle engine, prioritizing a compact footprint. This objective focuses on three key areas: turbocharger selection, combustor design, and comprehensive performance analysis. The selection of the turbocharger involved a rigorous evaluation of available models to identify the option delivering the optimal pressure ratio and airflow for the desired power output. Subsequently, the combustor design opted for a non-premixed configuration, offering advantages in terms of fuel versatility and potential NOx emission reduction. Using SolidWorks software, a simpler and optimized 3D model was created, prioritizing efficient fuel-air mixing and stable flame propagation within the compact constraints. To gain detailed insights into the non-premixed combustion process, the project utilized advanced ANSYS simulations. These simulations enabled profound analysis of critical parameters such as temperature distribution, pollutant formation, and overall combustion efficiency. In conclusion, this project successfully demonstrated the feasibility of developing a simple, compact, and potentially highly efficient Brayton cycle engine by employing a carefully selected turbocharger and a well-designed non-premixed combustor. Further refinements and experimental testing are recommended to validate the simulation results and further optimize the design for real- world applications.
