ABSTRACT

A numerical study is performed regarding entrance flow of a viscous incompressible fluid through rotating curved pipe of circular cross-section. The flow depends on the pressure gradient force, centrifugal force due to curvature and coriolis force due to rotation. The effects of all these forces result in interesting flow behaviours in the entry region which are analyzed in the present study. The mathematical model is established considering three dimensional momentum equation. The problem is solved by finite difference method in a computational mesh extending from the inlet immediately adjacent to the reservoir to the fully developed region.
