Preliminary Design and Numerical Simulation of 2D Ramjet Engine
Main Article Content
Abstract
This study examines the design and flow modelling of the ramjet Engine at efficient Mach values, focusing on its theoretical and mathematical foundations. This work presents a comprehensive investigation of ramjet engines, aiming to clarify their fundamental operating principles, examine design standards and performance optimisation methods, delve into Computational Fluid Dynamics (CFD) methods for internal process modelling, and identify current design obstacles. The outcome presents an optimal ramjet engine design, exhibiting efficiency at supersonic speeds between Mach 2.8 and 3.3. The subsonic speed at the combustion chamber is created by generating shock waves with the use of an inlet cone, with a cone angle of 35. The Mach number at the nozzle was increased by using dual bell nozzles.
