高速气流中二维定常火焰的解析处理
Analytical treatment of 2D steady flames anchored in high-velocity streams
摘要：
重新讨论了通道中高速气流的燃烧问题。以前对这个问题的处理被认为是不完整的。结果表明，尽管横向气体速度相对较小，但它在确定火焰结构中起着至关重要的作用。特别是，它是必要的，在制定火焰锚附近的边界条件，并为火焰传播规律的适当帐户。利用定常锚定火焰的壳上描述，给出了问题的一致解。得到了火焰前缘位置和前缘气流速度的计算公式。它表明，他们减少到一个二阶微分方程的前端位置。导出的方程的数值解。
英文摘要：
The problem of burning of high-velocity gas streams in channels is revisited. Previous treatments of this issue are found to be incomplete. It is shown that despite relative smallness of the transversal gas velocity, it plays crucial role in determining flame structure. In particular, it is necessary in formulating boundary conditions near the flame anchor, and for the proper account of the flame propagation law. Using the on-shell description of steady anchored flames, a consistent solution of the problem is given. Equations for the flame front position and gas-velocity at the front are obtained. It is demonstrated that they reduce to a second-order differential equation for the front position. Numerical solutions of the derived equations are found.
