Initial unsteady free convective flow past an infinite vertical plate with radiation and mass transfer effects

Khan A., Solanki R.

International Journal of Applied Mechanics and Engineering

2017

Vol. 22, no. 4

931--943

An exact solution and analysis of an initial unsteady two dimensional free convection flow, heat and mass transfer in the presence of thermal radiation along an infinite fixed vertical plate when the plate temperature is instantaneously raised, is presented. The fluid considered is a gray, absorbing emitting radiation but a nonscattering medium. Three cases have been discussed, in particular, namely, (i) when, the plate temperature is instantaneously raised to a higher constant value, (ii) when, the plate temperature varies linearly with time and (iii) when, the plate temperature varies non-linearly with time. A close form general solution for all the cases has been obtained in terms of repeated integrals of error functions. In two particular cases, the solutions in terms of the repeated integrals of error functions have been further simplified to forms containing only error functions. It is observed that for an increase in the radiation parameter N or a decrease in the Grashof number Gr or Gm, there is a fall in the velocity or temperature, but compared to the no radiation case or no diffusing species, there is a rise in the velocity and temperature of the fluid.

Mass transfer effects on an unsteady MHD free convective flow of an incompressible viscous dissipative fluid past an infinite vertical porous plate

Reddy B. P.

International Journal of Applied Mechanics and Engineering

2016

Vol. 21, no. 1

143--155

In this paper, a numerical solution of mass transfer effects on an unsteady free convection flow of an incompressible electrically conducting viscous dissipative fluid past an infinite vertical porous plate under the influence of a uniform magnetic field considered normal to the plate has been obtained. The non-dimensional governing equations for this investigation are solved numerically by using the Ritz finite element method. The effects of flow parameters on the velocity, temperature and concentration fields are presented through the graphs and numerical data for the skin-friction, Nusselt and Sherwood numbers are presented in tables and then discussed.

The bulk temperature in free convection flow of Carreau fluid

Uscilowska A.

International Journal of Applied Mechanics and Engineering

2005

Vol. 10, no spec

111-117

The presented paper treats the free convection flow. The non-Newtonian fluid is under the consideration. There exist quite a lot of models of the non-Newtonian fluid, in the literature. The work proposes the model for Careau fluid. The main assumption for such fluid is the varying viscosity, dependent on the strain rate. For the Careau fluid the numerical experiment has been performed. Some remarks and conclusions are included.
