Abstract
Laminar mixed convection in a pipe with buoyancy due to thermal and/or
concentration gradients has been studied numerically for uniform heat flux and
concentration conditions at the interface. The results, for equal thermal and mass
diffusion Grashof numbers, show that the flow field is very different from those
corresponding to both forced convection and thermal mixed convection. The
effects of solutal buoyancy predominate near the inlet while those of thermal
origin determine the flow field far downstream.
1 Introduction
There are many processes in which fluid flow occurs in the presence of
temperature and/or concentration gradients : evaporatio
