Carbon-based membranes were manufactured by deposition of a polymeric precursor on asymmetric porous, ceramic substrates with tube channel geometry followed pyrolysis. As precursor, an unsaturated polyester resin prepared was used. The the carbon results first short substrate geometries (105 mm long single-channel tube), further scaling-up 19-channel (250 and 600 length) successfully performed....

In this paper, we investigate the effects of slip condition, transverse magnetic field and radiative heat transfer to unsteady flow of a conducting optically thin fluid through a channel filled with porous medium. Exact solution of the governing equations for fully developed flow is obtained in closed form. Detailed computations of the influence of the Grashof number, Hartmann number, slip para...

In this paper heat transfer of non-Newtonian fluid flow in an axisymmetric channel with porous wall is analyzed. Variational Iteration Method is used to get complete analytic solution for velocity and temperature profiles. Results show an acceptable agreement between this method results and numerical solution.Also the effects of different parameters are discussed through graphs. It can be found...

The effects of both wall slip conditions and heat transfer on the magnetohydrodynamics (MHD) peristaltic flow of a Maxwell fluid in a porous planar channel with elastic wall properties have been studied. Mathematical formulation is based upon the modified Darcy’s law. The analytical solution has been derived for the stream function and temperature under the assumptions of small wave number.The ...

The effect of heat transfer on peristaltic flow of a couple stress fluid through a porous medium in a two dimensional flexible channel was studied under long wave length approximation. A Closed form of expressions is derived in terms of wall slope parameter for axial velocity, temperature and heat transfer coefficient using perturbation method. The effects of pertinent parameters of interest on...

This paper investigates steady-state solutions to MHD thermally radiating and reacting thermosolutal viscous flow through a channel with porous medium. The reaction is assumed to be strongly exothermic under generalized Arrhenius kinetics, neglecting the consumption of the material. Approximate solutions are constructed for the governing nonlinear boundary value problem using WKBJ approximation...
