摘要
通过对气缸内空气动量矩流率的分析 ,提出了柴油机进气涡流始稳面形成的一个新判据———动量矩流率准则 ,即缸内空气主涡流动量矩流率与缸内空气总动量矩流率近似相等时 ,就形成了始稳面。利用该准则分析了四气门柴油机进气涡流的形成过程。
Through the analysis of the in cylinder angular momentum flux(AMF),a new criterion,i.e.angular momentum flux criterion is proposed for predicting the emergence of stable swirl formation interface.Stable swirl formation interface exists when the main swirl angular momentum flux is nearly equal to the in cylinder air total angular momentum flux.In cylinder swirl formation in a 4 valve diesel engine was investigated by this criterion.
