锥面间流体流动考虑流动惯性的近似解
An Approximate Solution Considering Flow Inertia between Conical Surfaces
-
摘要: 本文采用锥坐标下的Navier-Stokes方程式,利用迭代近似解法,求出了考虑流动惯性时锥面间流体流动的速度分布、压力分布以及流量的解析式;并对轴对称过流流动的外向流和内向流进行了比较.Abstract: In this paper,analytical calculation expressions of the pressure distribution,velocity distribution and the rate of the flow between conical surfaces are found by using the method of iterative approximate solution when the inertia terms of the Navier-Stokes equations in conical coordinates are taken into account.Furthermore,we compare the centrifugal flow with the centripetal flow of axisymmetrical passing flow.
