首先研究了数值模拟系统的主要体系结构并分析了并行计算基本原理,然后使用计算流体力学平台OpenFOAM建立湍流燃烧流动数值模拟系统并使用该系统在特定的燃烧室网格环境下对煤气和空气湍流射流扩散燃烧进行数值模拟.模拟实验结果表明:系统能够较好地展示煤气和空气湍流燃烧流动的反应特性,验证了系统设计的合理性,而且通过使用并行计算技术后发现计算速度也明显加快.%First,The main architecture of the numerical simulation system is studied and its parallel computing principles are analyzed, and then the system of numerical simulation of turbulent combustion flows was established by using the OpenFOAM CFD platform and the turbulent jet diffusion flame of gas and air was conducted to simulate in a particular combustion chamber grid environment by using the system. The simulation results show that the system can not only demonstrate good response properties of gas and air turbulent combustion flow to validate the system design' s rationality but also find that the calculation speed is accelerated significantly by means of parallel computing technology.
