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。
An analysis was conducted for the flame-sheet combustion of an oxidizing Blasius boundary layer flow over a parallel gasifying fuel surface, allowing deviation of the flow Prandtl and Schmidt numbers from unity. Explicit expressions were obtained for the flame location, flame temperature, and fuel gasification rate for given properties of the oxidizing flow and the fuel. An asymptotic solution was also derived for the Blasius equation with surface blowing, with good accuracy when compared to the numerical solution.
