摘要
提出了全封闭活塞式压缩机热力性能和流体流动的CFD模拟方法。模拟采用了一维稳态的模型 ,建立了通用的控制方程形式 (能量、动量和连续方程 ) ,充分考虑了各部分的换热和整个区域的热平衡 ,并对R1 2和R60 0a进行了模拟计算和对比。
A numerical method for simulating the thermal and fluid-dynamic behavior of hermetic compressors by using CFD in the whole compressor domain are presented. The fluid flow model is developed through integrating transient one-dimensional conservation equations of continuity, momentum and energy in all of the compressor elements. The model describing thermal behavior is based on heat balance in the components such as muffler, connecting tubes and orifices. The calculation of the thermodynamic and transport properties for different refrigerants at various conditions has been considered and some numerical results form a hermetic compressor are presented.
