Three-dimensional Numerical Simulation of Combustion Field in the Combustion Chamber

摘要

In order to study the effect of rotation on the combustion in the underwater vehicle,a two-phase turbulent combustion process is described with Reynolds stress turbulence model,eddy-dissipation turbulent combustion model,P-1 radiation model and particle tracking model of liquid. The flow in the rotating combustion chamber is simulated at two different working speeds,0?r/min and 1?000?r/min by Fluent software. The temperature,gas velocity,static pressure of wall and fuel concentration are computed and compared. The results show that the combustion in rotating combustor is faster and more effective.
