摘要
采用基于MPI的并行算法,以k-ε湍流模型为基础,对生物柴油混合燃料的燃烧过程进行了数值模拟计算,讨论了并行计算的加速比,并将计算结果与柴油的燃烧情况进行比较。结果表明:混合燃料的燃烧效果与纯柴油相似,NO排放没有明显升高,可以作为柴油的替代燃料使用。
Combustion simulation of bio-diesel mixture was carried out by parallel algorithm based on the MPI library. The model was used to simulate the turbulence. Then, the speedup of parallel computation was discussed, and the result of simulation was analysed. The result shows that the mixture is simiTar to diesel ,and the emission of NO doesn＇t rise markedly. It can be used in the diesel engine.
