Analysis and Simulation of Flow Field of Lubricant-immersioned Motors for Aero Pupms

浸油电机依靠轴瓦提供航空煤油流动所需的动力,设计一种直槽和螺旋槽配合的轴瓦,可以加速油的流动,更有利于散热。为了精确模拟浸油电机内部流体的流动状态,首先建立了流场的物理、数学模型;然后采用有限元流体计算软件Ansys Fluent,对浸油电机前轴瓦流道内部流场以及气隙内部流场进行了仿真分析,由后处理软件输出了流场速度、压力和温度云图,并得到了流体粘性损耗值。

The flow of aviation kerosene is powered by celerating the flow of aviation kerosene and being more bush with both straight slot and spiral slot were designed bearing bush in lubricant-immersionedmotors, for ac- advantageous to dissipate the heat, a kind of bearing in this paper. For an accurate simulation of flow state in lubricant-immersionedmotors, first of all, built both physical and mathematics models of flow. Then, a fi- nite element fluid computing software-Ansys fluent was used for a simulatiom analysis of the interior flow of the front bearing bush in lubricant-immersioned motorsand air gap, post-processing software was also used to out- put the Velocity, the distributions of pressure and temperature and the value of fluid viscosity.
