摘要
为了研究双螺杆压缩机的流场动力学特性,提出基于双螺杆压缩机的工作循环为一个理论循环的假设,建立其工作过程的数值计算模型,采用计算流体力学软件Fluent中的动网格技术对双螺杆压缩机的工作过程和流场动力学特性进行了动态模拟仿真。搭建了实验平台并研究分析了双螺杆压缩机的p-V变化规律,结果表明,仿真结果较好地吻合实验数据,验证了模型的正确性和模拟方法的有效性。
In order to study the flow field dynamics characteristics of a screw compressor,a numer- ical calculation model of the working process was established on the suppose where the working cycle of screw compressor was a theoretical cycle, the working process and the flow field dynamic character- istics were simulated through the CFD software of Fluent hy the dynamic mesh technology. Addition- ally, to verify the numerical calculation model is accurate and the simulation method is effective,exper- iments on studying the pressure--volume changes in screw compressor were carried out and the re- sults show that the simulation data are in good agreement with the experimental ones.
