ABSTRACT

This paper is devoted to the problems of experimental and numerical investigation of the flow field in the sprayer module of a combustion chamber with homogenization of a fuel−air mixture (MOHOM) developed at the Central Scientific-Research Institute of Aircraft Engines. The adopted technique of computation of flow is based on numerical integration of Reynolds equations written in terms of the velocity−pressure variables for the case of a stationary turbulent twisted flow of constant density. The work was aimed at development of the technique of calculating a twisted turbulent flow in regions of complex shape by comparing predictions with the experimental data obtained for the case of escape into an open space. The calculations have shown that the characteristics of flow at the exit from a swirler correspond to experimental data with an accuracy sufficient for practice, in both velocity profiles and dimensions of the zone of backflows. The technique developed was used to calculate the hydrodynamics of flow inside the sprayer module with a mixing chamber in order to elucidate the influence of the structure parameters of swirlers. Data were obtained in a wide range of change of flow twistings.
