Numerical investigation of the effects of magnetic field strength, thermal radiation, Joule heating, and viscous heating on a forced convective flow of a non-Newtonian, incompressible power law fluid in an axisymmetric stretching sheet with variable temperature wall is accomplished. The power law shear thinning viscosity-shear rate model for the anisotropic solutions and the Rosseland approxima...

A numeriea! investigation for forced convection in a constant-temperaJure parallel pkue channel wilh porous cavity and block alternately emplaced on lhe bottom plaJe is presented in this work. The Brinkman-Forchheimer-extended Darcy mode~ whil:h accounts for the effects of impermeable boundary and inertia, is used to characterize the flow field inside the porous region. Solutions of Ihe coupled...

Abstra t. In the present paper, a theoreti al analysis of entropy generation due to fully developed ow and heat transfer through a parallel plate hannel partially lled with a porous medium under the e e t of transverse magneti eld and radiation is presented. Both horizontal plates of the hannel are kept at onstant and equal temperature. An exa t solution of governing equation for both porous an...

OBJECTIVES To investigate the link between cigarette smoking and muscle strength in Japanese men. METHODS We used data on 4249 Japanese men, aged 43.3±13.9 years, in this cross-sectional investigation study. Grip strength and leg strength were measured as indicators of overall muscle strength. Meanwhile, subjects' cigarette smoking habits were recorded by trained medical staff. The effect of ...

We present a well-posed model for the Stokes/Brinkman problem with jump embedded boundary conditions (J.E.B.C.) on an immersed interface. It is issued from a general framework recently proposed for fictitious domain problems. Our model is based on algebraic transmission conditions combining the stress and velocity jumps on the interface Σ separating the fluid and porous domains. These condition...

The rheology of dense colloidal suspensions is sensitive to modifications in the surface properties of the particles. We are using lattice Boltzmann simulations to investigate the effects of polymer coatings on the squeezing flow between parallel plates. In this study, we used random arrays of stationary and mobile particles as the simplest models of the polymer coat. We have calculated the flo...

The Brinkman model is a unified law governing the flow of a viscous fluid in cavity (Stokes equations) and in porous media (Darcy equations). In this work, we explore a novel mixed formulation of the Brinkman problem. Introducing the flow’s vorticity as additional unknown, this formulation allows for a uniformly stable and conforming discretization by standard finite elements (Nédélec, Raviart-...

This article aims to study the thin film layer flowing on a vertical oscillating belt. The flow is considered to satisfy the constitutive equation of unsteady second grade fluid. The governing equation for velocity and temperature fields with subjected initial and boundary conditions are solved by two analytical techniques namely Adomian Decomposition Method (ADM) and Optimal Homotopy Asymptoti...

This article describes the effect of thermal radiation on the thin film nanofluid flow of a Williamson fluid over an unsteady stretching surface with variable fluid properties. The basic governing equations of continuity, momentum, energy, and concentration are incorporated. The effect of thermal radiation and viscous dissipation terms are included in the energy equation. The energy and concent...
