A Review of Leakage Flow in Centrifugal Blood Pumps
Artificial Organs, 2006Abstract: This article presents a new approach in determining the functional relationship between the leakage flow in a centrifugal blood pump and various parameters that affect it. While high leakage flow in a blood pump is essential for good washout and can help prevent thrombus formation, excessive leakage flow will result in higher fluid shear ...

Leakage characteristics of plug flow in the case of pipe leakage
The Canadian Journal of Chemical EngineeringAbstract In order to study the changes in two‐phase flow parameters after pipeline damage and the impact of gas injection on water leakage from damaged pipelines, experimental and simulation studies were conducted on the damaged pipelines.

Passive flow control of bileaflet mechanical heart valve leakage flow
Journal of Biomechanics, 2008Blood damage and platelet activation are inherent problems with present day mechanical heart valve designs. We investigate the approach of passive flow control applied to bileaflet mechanical heart valve (BMHV) flows as a means of optimizing leakage flow hemodynamics at length scales relevant to blood damage and platelet activation.

Tip Leakage Flow In a Mixed-flow Pump
The numerical results used to describe the special flow features/characteristics of the mixed-flow pump in this chapter were obtained by employing the computational methodology described in Chapter 3 which includes the pump model, mesh generation, turbulence models and their near wall treatment, and the boundary conditions.Wei Li +4 more

Through Flow Analysis and Leakage Flow of a Regenerative Pump
Transactions of the Korean Society of Mechanical Engineers B, 2003Flows in a regenerative pump were calculated for several flow-rates, using the CFX-Tascflow. The calculated results show the vortex structure in the impeller and side channel. The predicted performance shows considerable discrepancy from the measured values for low flow rates. Main source of the difference is the leakage flow of pump strongly affecting

The Interaction of Turbine Inter-Platform Leakage Flow With the Mainstream Flow
Volume 6: Turbo Expo 2005, Parts A and B, 2005Individual nozzle guide vanes (NGVs) in modern aero engines are often cast as a single piece with integral hub and casing endwalls. When in operation there is a leakage flow through the chord-wise inter-platform gaps. An investigation into the effect of this leakage flow on turbine performance is presented.

Behavior of Tip Leakage Flow in an Axial Flow Compressor Rotor
Volume 6: Turbomachinery, Parts A and B, 2006The current paper reports on investigations with an aim to advance the understanding of the flow field near the casing of a small-scale high-speed axial flow compressor rotor. Steady three dimensional viscous flow calculations are applied to obtain flow fields at various operating conditions.

On the leakage flow around gas bubbles in slug flow in a microchannel
AIChE Journal, 2015The leakage flow is that liquid does not push gas bubbles and leaks through the channel corners. This leakage flow was confirmed by tracking particles moving in the liquid film with a double light path method and was quantified by tracking the gas–liquid interface movement. The results show that leakage flow varies during bubble formation process.
