0引言数值模拟方法在研究大型过程装备的性能中已经得到越来越广泛的应用,但仍有较多问题亟待解决。对于大型过程装备而言,其外形尺寸大且内部结构复杂,分析计算过程将占用巨量计算机资源,使计算时间大大延长。此外,大部分过程装备数值模拟需要附加的物理模型如湍流、燃烧、传热、化学反应、旋 0 Introduction Numerical simulation methods in the study of large-scale process equipment performance has been more and more widely used, but there are still many problems to be solved. For large-scale process equipment, its large size and complex internal structure, the analysis and calculation process will take up a huge amount of computer resources, the calculation time is greatly extended. In addition, most process equipment numerical simulations require additional physical models such as turbulence, combustion, heat transfer, chemical reactions, spin
