摘要:
对往复式压缩机气阀的数值模拟研究进展进行了综述。通过分析发现：随着计算流体动力学学科的不断发展，应用CFD方法模拟气阀内流场对于了解多物理场随空间、时间的变化具有显著优势，根据内流场特点改进结构成为CFD模拟的应用方向，需要在完善多场耦合理论和提高模拟精度方面进一步开展研究。The research progress and application of numerical simulation for reciprocating compressor valve are reviewed in this paper. It shows that the numerical simulation of flow field inner valve is propitious to reveal the spatial distribution pattern of multi-physics field at different times, and the valve can be optimized through comparing several flow fields of different structures. Additionally, it is important to make some efforts on improving the multi-field coupling theory and simulation accuracy for the further development of reciprocating compressor.
