Integration of multi module flow domain to demonstrate the full engine aero-flow path simulation of Single Spool Turbojet Engine

Abstract The need for Full engine Simulations is gaining traction in multidisciplinary fields due to the complexity and comprehensiveness of this high fidelity computational analysis whereas Gas turbines, as key power producing devices, have wide ranging applications in aerospace, power generation, and marine engineering. As industries strive for enhanced engine performance and sustainability, understanding the complex behavior of gas turbines through simulation is essential for optimizing design, efficiency and is crucial in determining the design and off design behaviour and characteristics across flight envelope. This paper presents a comprehensive approach to full engine simulation, incorporating both standalone and integrated analysis methods. By understanding both the approaches, the study offers a holistic understanding of the engine’s performance, facilitating the identification of potential design improvements and operational optimizations. This analysis focuses on primary flow incorporating turbulence within the fluid domain. The results shown using contour plots represent critical performance parameters, such as Mach number and static pressure variations across the engine’s operating range. These contours allow for easy identification of better operating points and highlight performance trends across different subsystems and overall engine configurations.
