A study of the steady flow of blood through a horizontally symmetric artery with mild stenosis is presented by considering blood as a micropolar fluid. The viscosity of blood is considered as radial coordinate dependent. The non-linear pressure equations governing the flow are solved numerically using finite difference technique. The effects of micropolar fluid parameters and hematocrit on axia...

Polyethylene wear is a significant clinical problem in total knee arthroplasty (TKA). Although the tribology of joint replacement has consequently become an area of significant research, the effect of joint fluid on lubrication has been largely overlooked in the replaced joint. One factor that affects the tribology of metal on polyethylene articulation in joint prostheses is mechanical properti...

Amid the recent interest in the role of membrane viscosity in the deformation of a fluid-filled capsule, we consider the role of various capsule properties (shear elasticity, membrane bending stiffness and viscosity) in determining the response and recovery times of a spherical capsule in shear flow. These times are determined by fitting exponential functions to results for the Taylor deformati...

In this article, we have considered incompressible Jeffrey fluids and studied the effects of variable viscosity in the form of a well-known Reynold’s model of viscosity in an asymmetric channel. The fluid viscosity is assumed to vary as an exponential function of temperature. The governing fundamental equations are approximated under the assumption of long wavelength and low Reynold number. The...

In this paper aims, we found the fluid concentration after calculating velocity and temperature of with a variable viscosity that depends on moving through an inclined porous channel. We examined influences certain parameters are active by analyzing graphs obtained reached momentum equation solution, used MATHEMATICA program for plot two types flow (Poiseuille Couette).

In this paper, the wire coating analysis in MHD flow and heat transfer of a third grade fluid with variable viscosity in a porous medium with internal heat generation/absorption and Joule heating has been investigated. In the present study wire coating is carried out using melt polymer satisfying third grade fluid model. In the present discussion (i) Reynolds Model (ii) Vogel’s Model are consid...

The present investigation deals with study of laminar natural convection flow of a viscous fluid over a semi-infinite flat plate inclined at a small angle to the horizontal with internal heat generation and variable viscosity. The dimensionless boundary layer equations are solved numerically for a negatively inclined plate using a very efficient marching order implicit finite difference scheme....

A nanofluid is mixture of nano sized particles and a base fluid. This paper investigates by using laboratory based double pipe heat exchanger model, the performance of nanofluid containing about 48.46nm  particle size nanoparticles (ZnO) without or with addition of nonionic surfactant Rokanol K7 (500ppm) into the base fluid double distilled water to prepared three different concentrations 1.0%,...
