摘要
本文给出了环形槽道有压科特流层流的解析解,还提出了形状参数P,强调形状参数P可用作研究环形槽道有压科特流层流流动状态的判据,并讨论了当P值不同时,所研究流场中的速度极环面和速度拐环面存在的条件和它们的坐标。这对环形槽道有压科特流紊流的研究极有帮助。
This paper presents an analytical solution to laminal Couette flow with pressure gradient in a circular channel. As a criterion, the shape factor P is stressed. The existence and the location of extremum or deflection circular surfaces of velocity profiles in different P are disussed which might be of great use in the analysis of turbulent Couette flow.
