Abstract

In this study in order to predict the flow behavior, a numerical simulation in the tubular COMBUSTION CHAMBER with a wall jet is used.For this purpose, in order to analyze the flow field based on the experimental results, the method of finite volume with non-staggered grids is used and acceptable compliance with the available experimental results. The flow is considered to be three-dimensional, steady, turbulent, incompressible, viscous, two - phase and the TURBULENCE MODELs used include RNG (K-ε) model. The results indicate the presence of strong circulating area in dome region in non-reaction mode. With the chemical interactions, density of flow is increased and as the size of COMBUSTION CHAMBER is constant the increase in density leads to increase of central speed. As a result, the circulating area in dome region is almost eliminated. Also changes in rate of swirl air flow will result in increase of circulating flow in the primary area of COMBUSTION CHAMBER.Increase of air to fuel ratio rises the magnitude of velocities and profile of uniform in output. Finally, the optimum SAUTER MEAN DIAMETER and fuel spray angle is obtained.
