摘要
首先对机群系统的特点和软硬件配置环境进行阐述,然后基于MPI和开源工具OpenFOAM实现一个计算流体力学机群系统的搭建,并对这个机群系统的性能和并行效率进行测试和分析。通过利用此机群系统对湍流燃烧流动反应进行数值模拟及并行计算得到模拟效果的三维流场。实验结果表明,该机群系统针对湍流燃烧数值模拟可以明显提高计算效率并得到较好的仿真效果。
The characters of the cluster system and its software and hardware configuration environment are first described, then a computational fluid dynamics cluster system based on MPI and the open source platform OpenFOAM is constructed, and the per- formance and parallel efficiency of the cluster system are tested and analyzed. The numerical simulation and parallel computing for turbulent combustion flow reactor are achieved by using this cluster system and the three-dimensional flow field simulation results are obtained. The experiment results show that the cluster system for numerical simulation of turbulent combustion can improve the computational efficiency simaificantlv and get better simulation results.
