Optimization of Cowl Shock Interaction in a Ramjet Engine
摘要
This study focuses on improving ramjet engine thrust by integrating supersonic inlet cowls with primary and secondary pathways. The design aims to boost pressure ahead of the combustion chamber, enhancing combustion efficiency and thrust. Key innovations include a deflector and a slit for further optimization. Computational fluid dynamics (CFD) analysis is conducted at Mach 3, testing configurations with deflector angles of 20°, 25°, and 30°, paired with slit lengths of 20, 25, and 30 mm. Results reveal the most significant thrust enhancement at a 25° deflector angle, especially when combined with the secondary cowl inlet. This configuration demonstrates superior performance, validating the approach of leveraging optimized geometric features to maximize engine efficiency.
