一种全耦合多相流分析的并行计算方法

A PARALELL ANALYSIS METHOD FOR FULL COUPLED MULTIPHACE FLOW 1)

  • 摘要: 研究了孔隙介质中热、水和汽流全耦合分析的并行计算方法.模型中采用了考虑毛细压力关系的修正有效应力概念,并考虑了相变和潜热传递.基本变量为位移、毛细压力、汽压和温度.并行程序是在国家高性能计算中心(北京)的曙光1000A上借助PVM(ParalelVirtualMachine)软件系统实现的,考题显示出较高的并行加速比和效率

     

    Abstract: In this paper, we consider a full coupled multi phase problem involving heat and mass transfer in deforming porous media. The mathematical model consists of balance equations of mass, linear momentum and energy and of the appropriate constitutive equations. The chosen macroscopic field variables are temperature, capillary pressure, gas pressure and displacement. The gas phase is considered to be an ideal gas composed of dry air and vapour, which are regarded as two miscible species. The model makes further...
