BACKGROUND Implantation of a rotary blood pump (RBP) can cause non-physiological flow fields in the left ventricle (LV) which may trigger thrombosis. Different inflow cannula geometry can affect LV flow fields. The aim of this study was to determine the effect of inflow cannula geometry on intraventricular flow under full LV support in a patient specific model. METHODS Computed tomography ang...

A numerical study has been conducted to investigate the modelling of steady two-dimensional stagnation-point flow and diffusion of chemically reactive species of a viscous and incompressible fluid past a permeable quadratically stretching/ shrinking sheet. Similarity transformation has been used to reduce the governing nonlinear partial differential equations into a system of nonlinear ordinary...

The plasma flow in the scrape-off layer (SOL) plays an important role for the particle control in magnetic fusion reactors. The flow is expected to expel Helium ashes and to retain impurities in the divertor region, if it is directed towards the divertor plate. It has been experimentally observed, however, that the flow direction is sometimes opposite; from the plate side to the SOL middle side...

Liposomes are widely used as drug delivery systems in different forms including osmotic pumps, infusion and IV injection. In spite of these, there is no data available about their behavior under convective flow (e.g. infusion or osmotic pumps) and upon stagnation in such drug delivery systems. As a part of a series of investigations in this area, the present study investigates the effects of vi...

Abstract Liposomes are used widely as drug delivery systems in different forms including nanosuspensions, osmotic pumps, infusion pumps and IV injections. Some of these systems (e.g. infusion or osmotic pumps) might stay stagnant for a long time during or before administration, and therefore, might face phase separation. In spite of these, there is no data available about the behavior of lipos...
