本文通过解析方法分析了Pr与Sc不为1的情况下挥发燃料平面上平行氧化剂来流形成的边界层中的火焰面。对给定的物性,火焰位置和温度以及气化率可以被显式表达。同时也得到了和数值结果符合较好的挥发边界布拉休斯方程的近似解。
In this paper, we analyzed the flame surface in the boundary layer formed by the parallel oxidant flow on the volatilized fuel plane when Pr and Sc are different from 1. For a given physical property, flame position and temperature and gasification rate can be explicitly expressed. At the same time, we obtain the approximate solution to the Brac Hughes equation on the volatile boundary in good agreement with the numerical results.
