Abstract
Abstract The temperature rise of hydro-viscous film in rotating parallel disks is usually controlled by imposing throughflow for keeping high film viscosity, but the Coriolis effect induced by throughflow can resist hydro-viscous transmission in return. In this work, the combined effects of Coriolis force and temperature-viscosity dependency on the hydro-viscous transmission are investigated. Firstly, the momentum and energy equations are established and the temperature-viscosity relationship is given, meanwhile, the numerical method is introduced. Then the combined effects on temperature rise and viscous transmission are analyzed and partly validated in experiment. The results reveal that with throughflow rate increasing the resistant effect of Coriolis force can be more and more significant relatively to temperature-viscosity effect, so their balance should be highlighted.
