摘要：管道相交处的局部阻力系数通常由实验确定.试图根据局部阻力系数与边界几何形状的相关性,应用流体力学原理,以离散的方法研究某一过流断面的局部阻力系数,再用集合的方法计算相交处的局部阻力系数,以达到用数字计算方法代替实验方法.
The local resistance coefficient at intersecting pipes corner is determined usually by experiments. This paper tries according to the correlation between boundary geometrical shapes and local resistance coefficient and by using fluid mechanics principle and discrete method to study local resistance coefficient of a certain flow crosssection. Then the local resistance coefficient of intersection site is calculated by aggregation method so as to replace the experimental method with numerical calculation method.
