Heat transfer in a viscous fluid between two walls with constrictions

Abstract

Recently, the flow of an incompressible viscous fluid in a pipe whose cross-section varies harmonically along the axis was investigated by Uberoi from the magnetohydrodynamic point of view [1], by Belinfante from the ordinary hydrodynamic point of view [2] and by Farzetdinov from the natural convection point of view [3].
