Flow Through

In this article, the unsteady free convective flow through a rotating disk was discussed under the influence of the chemical reaction, Dufour effect and Soret effect. Similarity transformation is used to change the unsteady non-linear boundary equations to a set of ordinary differential equations. Then we used the MATLAB’s bvp4c solver to solve these differential equations. Temperature as well as concentration profiles are drawn for different flow parameters of flow such as Soret Effect, Dufour Effect and also parameter of Chemical Reaction. We have also discussed the Nusselt number graph and values are given in a tabular form for different kinds of flow parameters.

The effects of radiation and chemical reactions, in the presence of a transverse magnetic field, on free convective flow and mass transfer of an optically dense viscous, incompressible, and electrically conducting fluid past a vertical isothermal cone surface are investigated. The nonlinear boundary-layer equations with the boundary conditions are transferred by a similarity transformation into a system of nonlinear ordinary differential equations with the appropriate boundary conditions. Furthermore, the similarity equations are solved numerically by using a fourth-order Runge–Kutta scheme with the shooting method. Numerical results for the skin-friction coefficient, the local Nusselt number, the local Sherwood number are given; as well, the velocity, temperature, and concentration profiles are presented for a Prandtl number of 0.7, the chemical-reaction parameter, the order of the reaction, the radiation parameter, the Schmidt number, the magnetic parameter, and the surface temperature parameter.
