本文介绍了一种新的以压力、速度和焓为原始变量的预处理技术。该技术以时间推进算法为基础，统一了可压缩流体和不可压缩流体的计算流体力学方法。它可以处理可压缩、不可压缩和相变流体的流场。该方法可用于含空化流场的数值模拟。
A new preconditioning technology using the primal variables of pressure, velocity and enthalpy is introduced in this paper. This technology, based on time-marching algorithm, unified the methods of CFD for compressible and incompressible fluid. It can deal with the flow fields with compressible, incompressible and phase transitional fluid. It can be used to simulate the flow field with cavitation.
