摘要
以某微型离心压气机为例,利用UG软件对该压气机进行建模,使用NUMECA87.3软件进行数值模拟计算,获得了压气机的流场分布情况,主要包含压力场分布参数和速度场分布参数。将计算得到的结果与压气机实际的试验结果进行对比分析,结果表明,数值模拟计算方法得到的数据与试验结果接近,说明网格划分较合理,流场的边界条件选取符合客观规律,计算方法合理可行,通过对数值模拟计算得到的离心压气机的特性规律及主要性能参数进行分析,为离心压气机后续的改进设计提供理论依据。
The NUMECA 87.3 is used to do numerical simulation compute on a small centrifugal compressor to get the flow field distribution situation of the compressor, mainly containing the pressure field distribution parameter and the velocity field distribution parameter. Comparing the computed result with the testing result, the computed data is close to the testing data. So the grid dividing is suitable, the boundary condition of flow field is select according with the objective principle and the computational method is feasible. In conclusion, this method provides fundamental basis for the improvement design of the centrifugal compressor
