The influence of wall roughness on bubble drag reduction in Taylor-Couette turbulence [PDF]
, 2018 We experimentally study the influence of wall roughness on bubble drag reduction in turbulent Taylor-Couette flow, i.e.\ the flow between two concentric, independently rotating cylinders.

Fluid Flow Equations for Rotordynamic Flows in Seals and Leakage Paths [PDF]
, 2001 Fluid-induced rotordynamic forces produced by the fluid in an annular seal or in the leakage passage surrounding the shroud of a pump or turbine, are known to contribute substantially to the potential excitation forces acting on the rotor.

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 ...
