摘要
为了研究往复式天然气压缩机内部气体流场的分布规律,采用FLUENT数值模拟研究方法,通过研究压缩机在膨胀开始、膨胀中间、膨胀终止吸气开始、吸气中间、吸气终止压缩开始、压缩中间、压缩终止排气开始等代表性的运行过程中气体压力分布特征,得出了压缩机内部流场在运行过程中的变化规律。并且通过与理论工作循环的对比,验证了数值模拟的正确性。
In order to research the gas flow field distribution of reciprocating natural gas compressor, we used the FLUENT numerical simulation method, and we study the representative in the running process of the distribution characteristics of compressor in the expansion began, bulging, expansion end and suction begin, suction running, suction termination and compression begin, compressing, compression end and exhaust start. We obtained the variation of flow field in the compressor. And also verified the correctness of the numerical simulation by comparing with the theoretical cycle.
