Computational Analysis of Combustion Chamber Using Cavity-based fuel Injector with Non-Premixed Combustion Model

Abstract

This paper presents the supersonic combustion of hydrogen fuel using cavity-based fuel injector with two-dimensional turbulent non-premixed combustion model The present model is based on the standard k-epsilon two equations with standard wall functions which is P1 radiation model and a PDF Probability Density Function approach is created The hydrogen fuel is injected just upstream of the cavity The Contour of Mass fraction of OH indicates a little amount of OH around 0 001454 after combustion A cavity flame holder is provided which injects hydrogen fuel in a supersonic hot air stream that facilitates enhanced mixing and combustion efficiency
