| 摘 要： | 本文在通风管路流运过程及漏风特性进行流体力学及数值计算分析的基础上，建立了通风管路接头漏风的数值模型有订应的系统方程。运用漏风数值模型研究了风管直径、漏缝尺寸、阻力系数及管路长度对漏风的影响。研究结果与日本高木英夫公式不谋而合，证明本文构思正确，并具有一定的实用性。

| Abstract: | A numerical model of air leakage through coupling of ventilating air duct and corresponding system function were put forward on the basis of analysis by fluid mechanics and numerical calculation. As an example the numerical model was applied on researching of the effects of air duct diameter;coupling seam dimension, resistance factor and the length of air duct on the leakage. The result of investigation happened to coincide with that of Mr. Takaki of Japan,proving that the numerical model in question is correct and applicable. |
