The objective of this investigation is to analyze the effect of unsteadiness on the mixed convection boundary layer flow of micropolar fluid over a permeable shrinking sheet in the presence of viscous dissipation. At the sheet a variable distribution of suction is assumed. The unsteadiness in the flow and temperature fields is caused by the time dependence of the shrinking velocity and surface ...

The heat transfer Magnetohydrodynamics flows have been potentially used to enhance the thermal characteristics of several systems such as exchangers, electromagnetic casting, adjusting blood flow, X-rays, magnetic drug treatment, cooling nuclear reactors, and devices for cell separation. Our concern in this article is numerically investigate flow an incompressible micropolar fluid with transpor...

This paper was concerned with studying the magnetohydrodynamic steady laminar free convection flow of a micropolar fluid past a continuously moving surface in the presence of heat generation and thermal radiation. Similarity transformation was employed to transform the governing partial differential equations into ordinary ones, which were then solved numerically using the finite element method...

In the present paper, the problem of reflection and transmission of waves at an interface of elastic and microstretch thermoelastic solids with microtemperatureshas been studied. The amplitude ratios of various reflected and transmitted waves are functions of angle of incidence and frequency of incident wave. The expressions of amplitude ratios have been computed numerically for a particular mo...

In the present manuscript, we investigated a two dimensional axisymmetric problem of nonlocal microstretch thermoelastic circular plate subjected to thermomechanical sources. An eigenvalue approach is proposed to analyze the problem. Laplace and Hankel transforms are used to obtain the transformed solutions for the displacements, microrotation, microstretch, temperature distribution and stresse...

Dilatancy is of importance for understanding the micromechanical behavior materials such as cemented sand, mortar joints, and interfaces masonry-like structures. Rough interface contacts are able to result in dilatancy lead an increase material’s volume. However, far authors’ knowledge very few works present regarding phenomenon composite materials. The work aims at investigating effect on with...

The present study is concerned with the propagation of Lamb waves in a homogeneous isotropic thermoelastic micropolar solid with two temperatures bordered with layers or half spaces of inviscid liquid subjected to stress free boundary conditions. The generalized theory of thermoelasticity developed by Lord and Shulman has been used to investigate the problem. The secular equations for symmetric...

The current work deals with the pulsating flow of Au-blood micropolar nanofluid existence thermal radiation and Joule heating. Micropolar fluid is addressed as blood (base fluid) Au (gold) a nanoparticle. has been mathematically modeled, resulting in delicate system partial differential equations (PDEs). A perturbation technique used to convert PDE into ordinary (ODEs), which are subsequently s...
