The influence of the partial surface wetting on the flow field in a pipe with circular cross-section

Abstract

In this paper the study of laminar flow in a pipe with a slip boundary is presented. The influ-ence of the partial surface wetting on shear and velocity profile as well as pressure drop has been investigated numerically. Steady, isothermal, incompressible flow was modelled in 2D and 3D geom-etry. Wall boundary condition was modified through the user defined function to account for partial surface wettability based on the theory proposed by Pochylý [1-10]. The results obtained by numeri-cal modelling in Fluent were compared with theoretical assumptions.
