Abstract: Dimensional considerations on the torque coefficient of coaxial cylinders, inner one rotating and outer one at rest, result in the expression CM = f(T/Ri , Re) where Re is the Couette Reynolds ...

Abstract: The leakage and frictional characteristics of helical flow in concentric cylinders with fine clearance have been studied for the ratio of clearance to radius from 0.0006 to 0.0127 and the ratio ...
