An unsteady, two-dimensional, hydromagnetic, laminar mixed convective boundary-layer 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...

The effect of radiation on unsteady Couette flow between two vertical parallel plates with ramped wall temperature have been studied. The fluid considered here is a gray, absorbing/emitting radiation but a non-scattering medium. An analytical solution of the governing equations has been obtained by employing Laplace transform technique. The influence of the various parameters, entering into the...

In this paper, forced and free convection in the cavity is simulated numerically with complex boundary conditions. Temperature changes sinusoidally at the upper and right walls and the temperature of the other walls is kept at zero. The effects of Prandtl and Grashof numbers variations on flow patterns are surveyed. A wide range of materials, e.g. molten metals, gases, water, and coolant liquid...

This article studies fluid dynamics and convection of the geothermal system. Earthquakes cause faults. Fault zones come up with pathways for convection. These paths have different characteristics space distribution, causing challenge to investigate The cavity considered in study is normally found energy reservoirs. An unsteady, incompressible, laminar flow along studied. finite element method (...

The problem of unsteady MHD free convection flow and mass transfer near a moving vertical plate in the presence of thermal radiation has been examined in detail in this paper. The governing boundary layer equations of the flow field are solved by a closed analytical form. A parametric study is performed to illustrate the influence of radiation parameter, magnetic parameter, Grashof number, Pran...

Investigation of the effect of thermal radiation on a fully developed magnetohydrodynamic (MHD) convective flow of a Newtonian, incompressible and electrically conducting fluid in a vertical microchannel bounded by two infinite vertical parallel plates with constant temperature walls through a lateral magnetic field of uniform strength is presented. The Rosseland model for the conduction radiat...

This paper is concerned with the asymptotic stability derived for two-dimensional incompressible Navier–Stokes equations multidelays on Lipschitz domain, which models control theory of 2D fluid flow. By a new retarded Gronwall inequality and estimates stream function Stokes equations, complete trajectories inside pullback attractors are asymptotically stable via restriction generalized Grashof ...

In this work we address the effect of particle inertia on depositional particulate density currents. We employ a two-fluid model based on the equilibrium Eulerian approach and present highly resolved two-dimensional (2D) simulations of the flow for a Reynolds number of 3450 (this particular choice corresponds to values of Grashof number Gr of 1:5 10).The simulations capture physical aspects of ...

Thermosolutal convection in a square cavity filled with air and submitted to an inclined magnetic field is investigated numerically. The cavity is heated and cooled along the active walls with a mass gradient whereas the two other walls of the cavity are adiabatic and insulated. Entropy generation due to heat and mass transfer, fluid friction and magnetic effect has been determined in transient...
