Abstract

Flow field calculation of oil-gas two-phase is the basis of the heat and mass transfer study in the aero-engine bearing chamber. In order to analyze the oil-gas interaction in two-phase flow field, the oil/air two-way coupled numerical model is proposed in this paper, the distributions of vortex, velocity and turbulence kinetic energy in a simplified bearing chamber are calculated, and the comparison between two-way and one-way coupled calculation results is carried out. Results show that the addition of oil has a great influence on the two-phase flow field, the mainstream difference between two-way and one-way coupled calculation is at least 10%, and therefore the effect of oil droplets to air flow cannot be ignored in the calculation of two-phase flow. Furthermore, the flow vortex and turbulence kinetic energy will also change with the effect of oil droplets.
