In a composite layer that comprises of porous which is sparsely packed and saturated with two component incompressible fluid above this lays the same fluid, variable heat sources or sinks in both layers double diffusive non-Darcian Benard Marangoni (DDNBM) convection investigated. The upper surface has effects depend on temperature concentration, whereas lower rigid. inverted parabolic, parabol...

Air film cooling has been successfully used to cool gas turbine hot sections for the last half century. A promising technology is proposed to enhance air film cooling with water mist injection. Numerical simulations have shown that injecting a small amount of water droplets into the cooling air improves film-cooling performance significantly. However, previous studies were conducted at conditio...

In this study, the pulsating flow of a non-Newtonian fluid and heat transfer in pipe with uniform flux at its wall is examined analytically. The assumed to be both hydrodynamically thermally fully developed. perturbation method based on series expansion used analysis. periodic change period-averaged values friction factor Nusselt number as well velocity temperature profiles are obtained varying...

The aim of this paper is to investigate the effect of the variable thermal conductivity and the inclined uniform magnetic field on the plane Poiseuille flow of viscous incompressible electrically conducting fluid between two porous plates Joule heating in the presence of a constant pressure gradient through non-uniform plate temperature. It is assumed that the fluid injection occurs at lower pl...
