Recent investigations into convection in Europa’s ice shell have been based on nonNewtonian (stress-dependent) or Newtonian (stress-independent) viscosity for water ice. However, despite the wide use of Newtonian convection, experimentally observed water ice flow is non-Newtonian, and analysis of stability against convection of the ice shell using updated flow laws has been only performed for n...

A numerical investigation of Newtonian and non-Newtonian steady blood flow in a complete idealized threedimensional venous model have recently been shown to provide prognostically relevant for hemodynamic data. The geometry reconstruction is essencial for the assessment of clinically relevant hemodynamic parameters. The blood flow patterns influence the development of thrombus that remains a si...

This study investigated the significance of symmetry and non-symmetry stenosis effects of blood flow and quantifies some of the most relevant non Newtonian characteristics of blood flow in blood vessels. The models studied in this work are the Newtonian and Non-Newtonian (Oldroyd-B) models, as well as their generalized (shear-thinning) modifications. The governing system of equations is based o...

In this work, non-Newtonian effects on Low-Density Lipoprotein (LDL) transport across an artery are analyzed with a multi-layer model. Four rheological models (Carreau, Carreau-Yasuda, power-law and Newtonian) are used for the blood flow through the lumen. For the non-Newtonian cases, the arterial wall is modeled with a generalized momentum equation. Convection-diffusion equation is used for th...

the galerkin finite element method is used to solve the three dimensional continuity, momentum and energy equations for laminar newtonian and power-law model non-newtonian flow through horizontal circular tube. the governing equations are non-dimensionalized with respect to specific variables and converted into algebraic equations using appropriate elements. to accelerate convergence a combinat...

In this paper, the Ritz-Galerkin method in Bernstein polynomial basis is applied for solving the nonlinear problem of the magnetohydrodynamic (MHD) flow of third grade fluid between the two plates. The properties of the Bernstein  polynomials together with the Ritz-Galerkin method are used to reduce the solution of the MHD Couette flow of non-Newtonian fluid in a porous medium to the solution o...
