Abstract

enIn the field of air propulsion, propulsion by means of scramjet offers wide possibilities of use. This type of airbreathing engine operating in hypersonic mode would offer an alternative to rockets. One of the constraints to the development of this type of reactor is the shock train phenomenon. It consists of a series of oblique shocks caused by the pressure emanating from the combustion chamber and the interaction of these shocks with the boundary layer. To allow the flow to stabilize, an insulator is placed between the inlet and the combustion chamber. The objective of this work is to simulate the flow taking place in this insulator by modifying the algorithm developed by Professor M. Papalexandris. Terms related to viscosity and heat conduction have been added to the second-order non-fragmented algorithm solving the Euler equations for non-viscous reactive flow. The influence of parameters such as insulator geometry, back pressure, initial flow velocity and boundary layer thickness will be investigated using the results of simulations performed with the program developed in this work.
