The analysis result of velocity distribution and boundary layer thickness is put forward in the boundary layer and cored region for laminar and turbulent flow of pipeline.
采用动量积分方法推出了管道流动中的速度边界层方程,给出了管道层流和紊流时速度边界层和核心区中的速度分布、边界层厚度的解析结果,并与冯。
The computation results showed that the effect of density differences when velocity of flow was small was obvious to the boundary of laminar flow in the elevation difference pipeline.
结果表明,在大落差管道,流速不大的情况下,密度差对层流边界层影响比较明显。
