in this paper the heating process in a box annealing unit is simulated and the effect of various parameters involved in the process is examined. for this purpose, the full naiver-stokes equations along with the standard k- turbulence model are solved in the fluid region using the finite volume approach. in the solid area the conduction heat transfer equation is employed using approporate surfac...

The slow motion of a body through a stratified fluid bounded laterally by insulating walls is studied for both large and small Peclet number. The Taylor column and its associated boundary and shear layers are very different from the analogous problem in a rotating fluid. In particular, the large Peclet number problem is non-linear and exhibits mixing of statically unstable fluid layers, and hen...

(i) For laminar flow (1) has been derived in [7] for f = −H ′′. A first analysis of that case is in [6]. Moreover this equation is also considered in the context of shock profiles in plasmas [2]. (ii) For turbulent flow in a certain distinguished limit concerning the Reynolds number and the Froude number eq. (1) has been derived in [3,4] with f = H . A multiple scales analysis of the full flow ...

Objective of the present investigation is intended to study MHD Casson fluids flow through an exponentially stretching surface. This free convective in?vestigated in thermally stratified porous medium. Also viscosity along with thermal conductivity varying temperature. With exponential decay for inter?nal heat generation region and buoyancy force, natural-convection induced. Then transformed se...

Stratified two-phase flow regimes can occur in the main cooling lines of Pressurized Water Reactors, Chemical plants and Oil pipelines. A relevant problem occurring is the development of wavy stratified flows which can lead to slug generation. In the last decade, the stratified flows are increasingly modelled with computational fluid dynamics (CFD) codes. In CFD, closure models are required tha...
