通过基于标准的κ-ε方程湍流模型，采用SIMPLEC算法求解N-S方程，利用CFD嵌入式滑移网格技术对双吸平衡式螺杆压缩机整机工作过程进行非定常数值模拟。对螺杆压缩机从吸气、压缩到排气整个工作过程的压力分布、温度分布、速度分布以及排气座回流、涡流分布情况进行了分析，从而为双吸平衡式螺杆压缩机排气口设计以及优化提供有利的依据。

Based on the standardκ-εturbulence model,SIMPLEC was used to solve the N-S e-quations in this paper,and CFD sliding mesh method was applied to conduct the unsteady nu-merical simulation on the whole process of double suction balance type screw compressor.The pressure,temperature,velocity,suction and exhaust backflow and eddy distribution of the whole working process,which consist of suction,compress and exhaust,were analyzed.The simula-tion results provide favorable basis for the screw compressor suction,exhaust design and the op-timization of double suction balance type screw compressor.
