A mathematical analysis has been presented to study the effect of a mild stenosis on blood flow characteristics with the representation of blood by couple stress fluid. The equations governing the flow of the proposed model are solved and closed form expressions for the blood flow characteristics, namely, dimensionless resistance to flow and wall shear stress at maximum height of the stenosis a...

Abstract Based on the couple-stress theory, elastohydrodynamic lubrication (EHL) contact is analyzed with a consideration of size effect. The lubricant between surface homogeneous coated half-plane and rigid punch supposed to be non-Newtonian fluid. density viscosity are dependent fluid pressure. Distributions film thickness, in-plane stress, pressure calculated by solving nonlinear fluid-solid...

The impact of non-uniform temperature gradients on Rayleigh-Darcy convection in a composite system couple stress fluid is discussed. bounded by stress-free surfaces and adiabatically insulated, the fluid-porous layers are coupled employing appropriate interfacial boundary conditions. To determine eigen value, regular perturbation method used. effect dimensionless parameters analysed graphically...

‎in this paper‎, ‎we have investigated the chaotic behavior of thermal convection in couple stress liquid saturated porous layer subject to gravity‎, ‎heated from below and cooled from above‎, ‎based on theory of dynamical system‎. ‎a low dimensional lorenz‎- ‎like model is obtained by using galerkin-truncation approximation‎. ‎we found that there is proportional relation between scaled couple ...
