This mathematical model explains the behavior of sinusoidal radius activity in stagnation point three-dimensional flow hybrid nanoparticles through a circular cylinder. The energy equation heat source/sink effect and mass Arrhenius activation chemical reaction effects are incorporated. Self-relation transformations adopted to reduce PDEs ODEs, then RKF-45 method is solved with shooting proficie...

An unsteady, two-dimensional, hydro magnetic, laminar mixed convective boundarylayer flow of an incompressible, Newtonian, electrically-conducting and radiating fluid along a semi-infinite vertical permeable moving plate with heat and mass transfer is analyzed, by taking into account the effect of viscous dissipation. The plate moves with a constant velocity in the direction of fluid flow while...

In this paper we analyze the combine influence of radiation and dissipation on the convective heat and mass transfer flow of a viscous fluid through a porous medium in a rectangular cavity using Darcy model. Making use of the incompressibility the governing non-linear coupled equations for the momentum, energy and diffusion are derived in terms of the non-dimensional stream function, temperatur...

A similarity solution is proposed for the analysis of steady free convection heat and mass transfer over a stretching sheet. The effect of radiation, chemical reaction and variable viscosity on hydromagnetic heat and mass transfer in the presence of magnetic field are investigated. The governing partial differential equations are transformed to the ordinary differential equations using similari...

In this paper, we study the chemical reaction and heat source effects on unsteady MHD free convection heat and mass transfer of a nanofluid flow past a semi-infinite flat plate in a rotating system. The plate is assumed to oscillate in time with steady frequency so that the solutions of the boundary layer are the similar oscillatory type. The innovation of the present work is closed-form analyt...

The problem of unsteady, laminar, coupled heat and mass transfer by MHD mixed convective boundary-layer flow of electrically conducting fluid over impulsively stretched vertical surface in an unbounded quiescent fluid with aiding external flow in the presence of a transverse magnetic field and melting effects is considered. The flow is impulsively set into motion rest and both of the temperatur...

A self-similar solution of unsteady mixed convection flow on a rotating cone embedded in a porous medium saturated with a rotating fluid in the presence of the first and second orders resistances has been obtained. It has been shown that a self-similar solution is possible when the free stream angular velocity and the angular velocity of the cone vary inversely as a linear function of time. The...
