Momentum, Heat and Mass Transfer in Logarithmic Spiral Flows of Incompressible Viscous Fluids*
نویسنده
چکیده
AL&met--This paper presents a theoretical investi~tion of the transfer of momentum, heat and mass in incompressible viscous how through a logarithmic spiral channel. The velocity, temperature and concentration profiles are calculated by the direct integration of the ordinary differential equations obtained from the governing transfer equations by means of the similarity tr~fo~ation technique. Numerical results are obtained for the shear stress and the rates of heat and mass transfer at the channel walls. As a special case, the analytical solution in a closed form is given for circular Couette flow. Results may be applied to the vapor-heated Rosenblad-TV spiral plate heat exchanger and the

Possessions of viscous dissipation on radiative MHD heat and mass transfer flow of a micropolar fluid over a porous stretching sheet with chemical reaction
This article presents the heat and mass transfer characteristics of unsteady MHD flow of a viscous, incompressible and electrically conducting micropolar fluid in the presence of viscous dissipation and radiation over a porous stretching sheet with chemical reaction. The governing partial differential equations (PDEs) are reduced to ordinary differential equations (ODEs) by applying suitable si...

In the present analysis, the Dufour and Soret effects on unsteady heat-mass transfer of a viscous incompressible Powell-Eyring fluids flow past an expanding/shrinking permeable sheet are reported. The fluid boundary layer develops over the variable sheet with suction/injection to the non-uniform free stream velocity. Under the symmetry group of transformations, the governing equations along wit...

The paper aims at investigating the effects of chemical reaction and thermal radiation on the steady two-dimensional laminar flow of viscous incompressible electrically conducting micropolar fluid past a stretching surface embedded in a non-Darcian porous medium. The radiative heat flux is assumed to follow Rosseland approximation. The governing equations of momentum, angular momentum, energy, ...
متن کاملEffects of Slip and Heat Transfer on MHD Peristaltic Flow in An Inclined Asymmetric Channel
Peristaltic transport of an incompressible electrically conducting viscous fluid in an inclined planar asymmetric channel is studied. The asymmetry is produced by choosing the peristaltic wave train on the walls to have different amplitude and phase. The closed form solutions of momentum and energy equation in presence of viscous dissipation term are obtained for long wave length and low Reynol...
متن کاملUnsteady Heat and Mass Transfer Near the Stagnation-point on a Vertical Permeable Surface: a Comprehensive Report of Dual Solutions
In this paper, the problem of unsteady mixed convection boundary layer flow of a viscous incompressible fluid near the stagnation-point on a vertical permeable plate with both cases of prescribed wall temperature and prescribed wall heat flux is investigated numerically. Here, both assisting and opposing buoyancy forces are considered and studied. The non-linear coupled partial differential equ...
