A Numerical Study of Drop Motion in Poiseuille Flow
The cross-stream migration of a deformable drop in two-dimensional Poiseuille flow at finite Reynolds numbers is studied numerically. In the limit of a small Reynolds number (<1), the motion of the drop depends strongly on the ratio of the viscosity of the drop fluid to the viscosity of the suspending fluid. For a viscosity ratio 0.125, the drop moves toward the centre of the channe while for t...

متن کاملNumerical Simulation of the Motion of a Drop in Plane Poiseuille Flow: Density Ratio Effects
Morteza Bayareh Department of Mechanical Engineering, Young researchers Club, Lamerd Branch, Islamic Azad University, Lamerd, Iran Abstract The density ratio effects on the motion of a three-dimensional drop in Poiseuille flow are examined at finite Reynolds numbers using a finite difference front tracking method. The elliptic pressure equation is solved by a multi-grid method. For deformable d...
متن کاملSequential Implicit Numerical Scheme for Pollutant and Heat Transport in a Plane-Poiseuille Flow
A sequential implicit numerical scheme is proposed for a system of partial differential equations defining the transport of heat and mass in the channel flow of a variable-viscosity fluid. By adopting the backward difference scheme for time derivative and the central difference scheme for the spatial derivatives, an implicit finite difference scheme is formulated. The variable-coefficient diffu...
متن کاملTransient Start-up of Plane Poiseuille Flow
INTRODUCTION This article investigates various improvements to two existing finite volume (fv) algorithms, specifically constructed to solve transient viscoelastic flow problems. Here, we consider model problems to identify fundamental algorithmic advances. Two alternative fv-approaches are advocated and contrasted for their properties, a hybrid cell-vertex scheme and a cell-centred staggered-g...
