摘要

考虑了具有自相似解的层流射流问题。给出了在给定边界条件下，只有一个自相似参数的自相似变量方程解存在的条件下，确定自相似参数的一种方法。在平面自由射流和壁面射流问题中，用解析法确定了自相似参数。在三维壁面射流问题中，利用神经网络确定了自相似参数。

On Self-Similarity of Laminar Jets

The problems of laminar jets that admit self-similar solutions are considered. A method for determining the self-similarity parameter is proposed based on the condition of existence of a solution to equations in self-similar variables under given boundary conditions with only a single self-similarity parameter. In problems of plane free and wall jets the self-similarity parameters are determined analytically. In the problem of a three-dimensional wall jet, the self-similarity parameter is determined using a neural network.
