摘要
从有限宽度平板 Couette流动的速度分布解出发 ,导出了有限大矩形管道流量公式 .利用无穷大平板 Couette流动的流量公式 ,给出了由管道形状决定的流量系数函数 ,并分析了流量公式在大宽高比和小宽高比情况下的渐近行为 。
An exact solution of flow rate for the rectangular section conduit with finite width is obtained in this paper according to the exact solution of velocity distribution.Flow coefficient is defined as ratio of flow rate of finite width plane to infinite one.Further,the evolution behaviors both in large height width ratio and in small height width ratio are analyzed in detail,which leads to approximation formula for flow rate.
