| 摘 要： | 针对国外在喷注碰壁混合的研究现状和存在问题，成功地建立了一个较全面的三维流体喷雾碰壁模型，描述液滴碰壁后粘附，反弹／粘附，飞溅／附壁射流等各种现象，并对一典型燃烧室内的喷雾碰壁混合过程进行三维数值模拟，其计算结果与实验结果比较吻合，说明计算模型的构筑是正确的，具有较高的工程实用价值。

| Abstract: | A general three-dimensional model for the mixing of impinging spray has been
developed after analyzing the current state of development. It describes the key complex
phenomena such as stick, rebound/stick, splash/tangential jet of an impingement droplet
successfully. By means of the model, the process of spray wall impingement in a typical
combustion chamber has been simulated. Good consistency between prediction and
experimental results indicates that the model has great accuracy and pofential for
engineering applications. |
