| 摘 要： | 利用CFD模拟软件FIRE及发动机热力循环模拟软件BOOST对六缸柴油机的工作循环过程及缸内的喷雾与燃烧过程进行了模拟分析,在原型机的仿真计算结果与实验值符合较好的前提下,通过对缸内燃油分布的分析,提出了综合考虑燃烧室形状、涡流比及喷孔配置等多因素的最优配置方法.结果表明,将热力循环模拟和三维燃烧模拟结合起来,既有利于实验验证,又便于对柴油机的缸内工作过程进行深入的分析.

| Abstract: | A calculation of thermodynamic cycle and combustion of a six-cylinder diesel by thermodynamic simulation tool BOOST and CFD simulation tool FIRE which was implanted advanced moving-meshes technology is presented in this paper. The mathematical models in the simulation of fuel spray and breakup, mixture formation and combustion of a diesel are described.Based on detailed insight into the governing processes provided by the 3D simulation results, various aspects of the interaction of spray propagation and combustion with chamber geometry, turbine intensity and the number of injection holes are discussed. Finally, some optimized configurations which took into account all of the factors mentioned above have been proposed in this paper. |
