摘　　要：用具有大量控制单元的多维CFD模型耦合详细反应动力学模型,来模拟发动机燃烧过程,所需计算时间长,目前已超出可被人们接受的程度。采用并行计算可以缩短计算时间。本文提出了柴油机燃烧过程"分区化学反应分布式并行算法"和"神经网络在线学习分布式并行算法"。在Windows XP操作系统下,基于MPI并行编程环境,用Fortran语言开发了并行计算程序,并在6台同方AMD 3200+计算机系统上调试成功,且通过验证计算,获得了较理想的并行效率。The multi-dimension al CFD model with a large number of control units coupled with detailed kinetic model to calculate the engine combustion process is of time consuming and not accepted. Parallel computing can reduce computation time. This paper presents ＂partition chemical reaction distributed parallel algorithm＂and ＂parallel distributed online learning neural network algorithm＂. In the Windows XP operating system and based on MPI parallel programming environment, the Fortran parallel computing program is developed and successful commissioning in AMD 3200＋ computer system on 6 computers is achieved. By verifying the calculation, a more ideal parallel efficiency is obtained.
