Unsteady Flow Induced by Variable Suction on a Porous Disk Rotating Eccentrically with a Fluid at Infinity

Unsteady flow of a Newtonian fluid induced by eccentric-concentric rotation of a porous disk and the fluid at infinity

The unsteady flow of a Newtonian fluid produced by a sudden coincidence of the axes of a porous disk and the fluid at infinity has been investigated while they are initially rotating with the same angular velocity about non-coincident axes. The exact solutions of both the velocity field and the components of shear stress on the disk have been obtained with the use of the Laplace transform techn...

Magnetoviscous Effects on Axi-Symmetric Ferrofluid Flow over a Porous Rotating Disk with Suction/Injection

The present study is carried out to investigate the magneto-viscous effects on incompressible ferrofluid flow over a porous rotating disc with suction or injection on the surface of the disc subjected to a magnetic field. The flow under consideration is axi-symmetric steady ferrofluid flow of electrically non-conducting fluid. Karman’s transformation is used to convert the governing boundary la...

Heat Transfer Analysis on Rotating Flow of a Second-grade Fluid past a Porous Plate with Variable Suction

We deal with the study of momentum and heat transfer characteristics in a second-grade rotating flow past a porous plate. The analysis is performed when the suction velocity normal to the plate, as well as the external flow velocity, varies periodically with time. The plate is assumed at a higher temperature than the fluid. Analytic solutions for velocity, skin friction, and temperature are der...

Unsteady free convection oscillatory couette flow through a variable porous medium with concentration profile

In this paper we have studied the effect of free convection on the heat transfer and flow through variable porous medium which is bounded by two vertical parallel porous plates. In this study it is assume that free stream velocity oscillates with time about a constant mean. Periodic temperature is considered in the moving plate. Effect of different parameters on mean flow velocity, Transient ve...
