- W2363060046 abstract "In order to search a reasonable numerical model to simulate the flowing characteristic of the oil-air two-phase flow in a bearing chamber,a simplified test rig was set up.Various rules of air flow proportion at the vent and oil temperature rise at the scavenger under different operating conditions were obtained through this experimental investigation.Based on Mixture multiphase model and Eulerian multiphase model with standard k-e turbulence model and RNG(renormalization group) k-e turbulence model respectively,the universal computational fluid dynamics software Fluent was used to simulate the two-phase flow in a bearing chamber under some given operating conditions.The comparison shows that the relative error of oil temperature rise between the test result and the computational result under Mixture multiphase model with RNG k-e turbulence model is only 2.72 percent when rotate speed is 2 200 r/min.Therefore,this computational model is accurate at high speed,based on which the distribution characteristics of oil-air two-phase flow velocity field,pressure field and temperature field are acquired." @default.
