natural convection heat transfer has many applications in different fields of industry; such as cooling industries, electronic transformer devices and ventilation equipment; due to simple process, economic advantage, low noise and renewed retrieval. recently, heat transfer of nanofluids have been considered because of higher thermal conductivity coefficient compared with those of ordinary fluid...

A bounded function φ : G → C on an LCA group G is called Hartman measurable if it can be extended to a Riemann integrable function φ∗ : X → C on some group compactification (ιX , X), i.e. on a compact group X such that ιX : G → X is a continuous homomorphism with image ιX(G) dense in X and φ = φ ∗ ◦ ιX . The concept of Hartman measurability of functions is a generalization of Hartman measurabil...

Here magnetohydrodynamic (MHD) boundary layer flow of Jeffrey nanofluid by a nonlinear stretching surface is addressed. Heat generation/absorption and convective surface condition effects are considered. Novel features of Brownian motion and thermophoresis are present. A non-uniform applied magnetic field is employed. Boundary layer and small magnetic Reynolds number assumptions are employed in...

The purpose of this work is to study the effect of oscillatory MHD blood flow in stenosed artery. The analytical and numerical results are obtained for oscillatory MHD blood flow, which is assumed to be a Newtonian fluid. It was also assumed that the surface roughness is of cosine shaped and the maximum height of roughness is negligible, compared with the radius of un-constricted tube. The flui...

Blood flow is modeled as non-Newtonian micropolar fluid. The non-linear governing equations of continuum and momentum in the cylindrical coordinate are being discretized using a finite difference approach and have been solved iteratively ,through Crank-Nicolson method. The blood velocity distribution, volumetric flow rate and Resistance to blood flow at the stenosis throat are computed for vari...

This article concerns heat transfer analysis in pulsating flow a channel with walls having multiple symmetric constrictions. The is influenced by Lorentz force and thermal radiation. unsteady governing equations, simplified for low conducting fluids, are solved the finite difference method using stream–vorticity function formulation. effects of emerging parameters, including magnetic field para...
