The Influence of the Partial Surface Wetting on the Flow Field Between the Two Coaxial Cylinders

Abstract

The influence of the partial surface wetting on the flow field between the two coaxial cylinders, the inner of which rotates, has been investigated numerically. Wall boundary condition was modified to account for partial wettability based on the equation proposed by Pochylý for the general curved surface [1-10]. FLUENT software was applied to model the stationary viscous fluid flow in a narrow gap. Different boundary conditions were applied on the rotating wall of the inner cylinder. The results obtained by numerical modelling were compared with theoretical assumptions.
