摘要: 本文对大量实验结果的分析发现,在高温气流中直流式喷嘴后方燃油浓度(总浓度,即汽相加液相浓度)分布为正态分布.从这一思想出发给出了适合工程设计用,并有一定准确度的直流式喷嘴后方燃油浓度分布的计算公式。这样。用较简单的方法初步解决了高温条件下的直流式喷嘴后方燃油浓度场的计算问题。

Abstract: It has been found from quite a number of experimental results that the distribution of the fuel concentration (the total concentration i, e. the resultant concentration of both vapour and liquid phases) is normal distribution. According to this idea, the formula for calculation of the fuel concentration is obtained. This formula is useful for engineering purpose with desirable accuracy. Thus , the calculation of such fuel concentration field may be carried out in a simpler way.
