The purpose of this work is to study the effect of blood flow in an inclined tapered artery under MHD effect through porous medium. Blood is considered as an electrically conducting Newtonian fluid. In this model, the analytical expressions for the volumetric flow rate, pressure gradient, wall shearing stress, and velocity profile have been derived. The problem is described by the usual MHD equ...

A numerical investigation is carried out for single phase flow behavior and heat transfer characteristics inside herringbone microfin tube by using a commercial CFD code FLUENT. It solves the three-dimensional NavierStokes equations in strong conservation form. Turbulence closure is provided by the standard k- turbulent model with enhance wall treatment. Numerical results showed that herringbo...

In this work, we optimise microfluidic converging/diverging geometries in order to produce constant strain-rates along the centreline of the flow, for performing studies under homogeneous extension. The design is examined for both two-dimensional and three-dimensional flows where the effects of aspect ratio and dimensionless contraction length are investigated. Initially, pressure driven flows ...

A computational analysis of an annular converging-diverging (CD) and an altitude adaptive expansion-deflection (ED) nozzle is presented. Numerical results were generated using a 2D axisymmetric, pressure-coupled solver in conjunction with the Spalart-Allmaras turbulence closure model and second order spatial discretisation schemes. Results were recorded over a theoretical altitude range and com...

The main objective of the present study is to utilize a novel linearization strategy to linearize the convection terms of the quasi-one-dimensional Euler governing equations on collocated grids and to examine its shock-capturing capabilities. To avoid a pressure checkerboard problem on the collocated grids, it is necessary to utilize two velocity definitions at each cell face. Similarly, we def...

A one-dimensional leakage flow model for two-phase ammonia-water twin screw compressors is presented. The model takes into account viscous and acceleration forces and is based on three conservation equations and on the equation of state for homogenous NHiH20 mixture. The governing equations are solved with a finite difference method. Numerical shooting is used to find such inlet flow velocity a...
