1D scramjet model

Abstract

Renewed interest in hypersonic research has motivated a number of scientists to reinvestigate the efficacy and performance of supersonic combustion ramjets, colloquially known as "scramjets". In this thesis, a 1-D scramjet model is proposed which shall be able to simulate separated flows within the isolator as well as the pressure distributions in a scramjet combustor. The goal is to divine the trends and sensitivities that are most significant in a given engine design, as well as provide a platform for further research into supersonic combustion. The model accurately predicts the stagnation and static quantities within a scramjet and can simulate the trends found in real life experiments. The 1D model gives significant physical insight to scramjet operation as it establishes key trade offs that scramjet analysis necessitate.
