Bulletin of JSME, 1978 This paper presents one of the methods for deriving a turbulent lubrication equation and a solution for the equation. The turbulent lubrication equation in the study is developed by such a procedure that the wall shear stresses in pressure flows and shear flows are evaluated based on the friction law of fluid, and their stresses are applied to ...
