【摘要】 本文综合考虑湍流混合、分子扩散的作用,提出了一个新的NO生成计算模型。该模型采用化学动力学时间尺度和湍流时间尺度来考虑化学动力学和湍流混合对NO生成的影响。文中模拟了一台浅盆形燃烧室柴油机,对计算结果和实测结果进行了对比分析。研究表明,新模型计算的NO生成速率与实测结果有较好的一致性。更多还原

【Abstract】 A new NO formation model was presented,which was formulated to incorporate the effects of both chemical kinetics and turbulent mixing.The model was applied to simulate a diesel engine with quiescent combustion chamber.The results indicate that the predicted NO formulation from the new model agrees well with the measured data.更多还原
