Higher injection temperature makes flame lift-off length decrease uniformly and asymmetry increase slightly.
初始喷油温度的升高会造成火焰浮起长度的减小,但不对称性的变化并不明显。
To measure the flame lift-off length and evaluate its asymmetry, an evaluating coordinate system is built which contains two planes and one Angle.
然后建立了一个评价火焰浮起长度及其不对称性的评价平面系,该评价平面系包括两个平面和一个角度。
Surface proximity and swirl rotational speed are the two basic factors leading to flame lift-off asymmetry, but their influences on the flame lift-off length is not strong.
模拟的结果发现贴壁程度和涡流转速是产生火焰浮起长度不对称性的基础,但其对火焰浮起长度的影响并不显著;
