Numerical Simulations and Design of a Scramjet Intake Using Two Different RANS Solvers

Abstract

A numerical and experimental design study of a scramjet intake has been initiated at RWTH Aachen University. The paper presents an overview of the ongoing work on the numerical simulations using two different RANS solvers: FLOWer the well-known DLR code and the adaptive unstructured QUADFLOW. Several geometry concepts, e.g. 2D intake, 3D intake with or without sidewall compression and single or double ramp are investigated configurations. The influence of different geometries on the flow, especially on the separation bubble in the isolator inlet as well as transition effects, and intake efficiency is discussed. Several numerical simulations have been performed applying a variety of turbulence models. The numerical results are compared with experimental work done at DLR Cologne.
