伴有堆积层的管道速度分布规律研究

对具有固定床的水平管道断面的紊流速度分布进行研究。将整个断面分为两部分：一部分为弓形断面，另一部分为固定床断面。弓形断面的速度分布研究是基于圆形断面管道紊流的理论，并且结合一定的假设来数值模拟弓形断面管道的紊流速度分布规律。固定床断面的速度分布研究是基于Ergun理论，最后通过一定的边界条件将两部分断面速度分布组合成整个断面的速度分布。通过大量的实验证明：该研究方法及程序较好地模拟了此断面的紊流速度分布。

Research on the Distributing Law of Water Velocity in the Pipe with Cumulating Layer

Researched water veloci ty of fi lling up bed in portion section of horiz ontal pipe.Divided the whole section int o two sections.One was arching section,t he other was filling bed section.Water v e locity in the pipe with circular section has b een studied for a long time,and many exp erts attained advanced theory.So based on for-theory and some tentati ve to research theory of water velocity in pipe of arching section.Filling bed s ection is based on Ergun theory,many exp eriments proved that the theory and prog ram are correct.
