Flow field and heat transfer of a nanofluid, whose non-Newtonian behavior has been demonstrated in the laboratory, in a square enclosure have been numerically modeled and investigated. To estimate the viscosity of nanofluid, experimental data of Hong and Kim, 2012 have been used, and a new model has been proposed. Finally, the obtained results have been compared to those of Newtonian behavior. ...

mixed convection fluid flow and heat transfer of water-al2o3 nanofluid inside a lid-driven square cavity has been examined numerically in order to find the optimal distribution of discrete heat sources on the wall of a cavity. the effects of different heat source length, richardson number and grashof number on optimal heat source location has been investigated. moreover, the average nusselt num...

In this paper, the study of the steady two-dimensional flow of an incompressible viscous fluid with heat and mass transfer and MHD heat generation past a moving vertical plate with suction in the presence of viscous dissipation and chemical reaction is investigated. Using similarity variables, the governing partial differential equations are transformed into non-linear ordinary differential equ...

Several relations from the Kolmogorov theory of fully-developed threedimensional turbulence are rigorously established for finite-time averages over LerayHopf weak solutions of the Navier-Stokes equations. The Navier-Stokes equations are considered with periodic or no-slip boundary conditions and an external forcing term. The main parameter is the Grashof number associated with the forcing term...

this paper presents the results of a numerical study on the removal process of fluid particles under the influence of mixed convection in a horizontal channel with an open cavity. the bottom wall of the cavity is heated at a constant temperature (th), while the top wall is maintained at a relatively low temperature (tc). fluid with a uniform velocity (uo) and temperature (tc) is introduced into...

Hall effects on combined free and forced convective flow of a viscous-elastic incompressible electrically conducting fluid between the horizontal perfectly conducting plates under the action of a uniform transverse magnetic field applied parallel to the axis of rotation is studied. Exact solution of the governing equation is obtained in closed form. It is observed that Hall current exerts stabi...

A steady MHD free and forced convective viscous incompressible electrically conducting flow in a rotating channel under constant pressure gradient has been studied. An exact solution of the governing equations has been obtained in closed form. The numerical results for the velocity components, the induced magnetic field components and the temperature distribution are being presented graphically...

Rotation effects on MHD flow past an impulsively started vertical plate with variable mass diffusion is studied here. The governing equations involved in the present analysis are solved by the Laplace-transform technique. The velocity, concentration and skin friction are studied for different parameters like mass Grashof number, Schmidt number, magnetic field parameter, rotation parameter and t...

an analytical study was performed to study effects of thermo-diffusion and chemical reactions on a three-dimensional mhd mixed convective flow of dissipative fluid along an infinite vertical porous plate with transverse sinusoidal suction velocity. the parabolic partial differential equations governing the fluid flow, heat transfer, and mass transfer were solved using perturbation technique and...
