this paper presents the results of a numerical study on the heat transfer performance and the removal process of fluid particles under the influence of magnetohydrodynamic 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 of the channel is maintained at a relatively low temperature (tc). air wi...

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...

In film cooling experimental studies, due to the difficulty in measuring the surface heat flux variation, a Heat Flux Ratio (HFR) equation originally derived by Mick and Mayle [1], has been widely employed to calculate the surface heat flux distribution using the measured adiabatic film effectiveness and surface temperature. A close examination of the derivation process and applications of the ...

Control of a fluid velocity profile by injection and suction of non-ionized flow in presence of a uniform steady magnetic field has important technical applications. In this paper, the unsteady incompressible and viscous conducting fluid flow has been investigated in a circular channel. The channel wall has been assumed to be non-conducting and porous. It has been subjected to a uniform steady ...

the effect of welding residual stresses that was created in thin infill plate of steel plate shear wall system during constructional processes was studied in this research. residual stresses in a welded structure is the result of the non-uniform expansion and contraction and plastic deformation of the weld and surrounding base metal due to heating and cooling cycle, during welding process, this...

in the present study, mixed convection laminar flow around an adiabatic body in a lid-driven enclosure filled with nanofluid using variable thermal conductivity and variable viscosity is numerically investigated. the fluid around the body in the enclosure is a water-based nanofluid containing al2o3 nanoparticles. the vertical enclosure’s walls are maintained at constant cold temperature and the...
