A magnetic hydrodynamic MHD of an incompressible viscoelastic fluid over a stretching sheet with electric and magnetic dissipation and nonuniform heat source/sink has been studied. The buoyant effect and the electric number E1 couple with magnetic parameter M to represent the dominance of the electric and magnetic effects, and adding the specific item of nonuniform heat source/sink is presented...

This paper deals with the effect of heat and mass transfer with chemical reaction on MHD oscillatory flow through porous medium in the presence of heat source/sink in an asymmetric channel. Based on some simplifying assumptions, the governing momentum, energy and diffusion equations are solved and the analytical solutions for fluid velocity, temperature distribution, mass concentration, skin fr...

The effects of thermal radiation and heat transfer over an unsteady stretching surface embedded in a porous medium in the presence of heat source or sink are studied. The governing time dependent boundary layer equations are transformed to ordinary differential equations containing radiation parameter, permeability parameter, heat source or sink parameter, Prandtl number, and unsteadiness param...

the paper numerically presents laminar forced convection of a nanofluid flowing in a duct at microscale. results were compared with both analytical and experimental data and observed good concordance with previous studies available in the literature. influences of brinkman and reynolds number on thermal and hydrodynamic indexes have been investigated. for a given nanofluid, no change in efficie...

The onset of nucleate boiling in the flow of water through a microchannel heat sink was investigated. The microchannels considered were 275 lm wide by 636 lm deep. Onset of nucleate boiling was identified with a high-speed imaging system and the heat flux at incipience was measured under various flow conditions. An analytical model was developed to predict the incipient heat flux as well as the...

Supercritical flow through a horizontal pipe leads to non-uniform peripheral wall temperature distribution even when the heat flux is kept constant and uniform. This attributed lower transfer coefficient at top section where denser fluid tends sink. Hence, obtain uniform temperature, designed roughness devised. Uniform sand-grain employed only partly cover half of wall. Numerical simulations we...

The suspension of nanoparticles in fluid influences several properties the resulting fluid. Many production and manufacturing applications need knowledge heat transference mechanism nanofluids. current paper concerns influence non-uniform source/sink on (MoS 2 -Go/water flow) hybrid nanofluid flow (Go/water a Darcy - Forchheimer porous medium between two parallel infinite spinning disks occurre...
