Numerical Simulation of Scram-Jet Combustor Using Double Wall Injector
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 5
Abstract
development of efficient supersonic combustion scramjets is challenging with such a high speed flight within the atmosphere. The main focus of this study is to understand the fuel injection, fuel–air mixing, combustion in the high velocity and high enthalpy flow environment. A detailed cfd study was carried out to simulate the high speed reacting flows inside the combustion chamber. This paper presents the results of double wall injector having 0.295 mm diameter. The results obtained are very attractive and forced to think about the replacement of available fuel injector and enhanced the research to get more other way of fuel injection system so that the drawback of available fuel injector is completely eliminated. Using a double wall injector we get rapid air-fuel mixing with reduced pressure losses.
