双螺杆压缩机CFD仿真分析及实验验证
|
摘要
针对双螺杆压缩机流体域形状复杂并随时间变化的特点,运用STAR CCM+软件进行计算流体动力学(CFD)分析,并搭建试验平台验证分析结果的准确性。通过对比仿真监测点和与之相对应的试验实测点的压力,两者在压力值和压力波动周期等方面具有较好的一致性,验证了CFD分析结果的可信度。
In view of the complex and time changing characteristics of the fluid domain in the twin screw compressor,and in order to study it's performance characteristics in detail,used STAR CCM +software to do the computational fluid dynamics(CFD)analysis,and the experimental platform was built to verify the accuracy of the simulation results.By comparing the pressure values of the simulated monitoring points and the experimental measured points corresponding to them,both of them have good consistency in the pressure value and the period of pressure fluctuation.
