Influence of the Leakage Flow Tangential Velocity on the Loss Generation and Leakage Flow Kinematics in Shrouded Axial Compressor Cascades

Volume 6: Turbomachinery, Parts A and B, 2006
Although compressor blades have long been shrouded for aerodynamic and structural reasons, the impact of the leakage flow in the shroud cavities on passage flows has only recently been investigated. Furthermore, the tangential velocity of the leakage flow, set by the blading and the relative motion between rotating and stationary surfaces, has a strong

Unsteady Flows in Lines with Distributed Leakage

Journal of the Hydraulics Division, 1968
Unsteady, nonuniform flows in pipelines which experience leakage are analyzed. Particular attention is given to the orifice manifold. Plows in a continuous manifold can be treated in several ways: (1) When the leakage is of such magnitude that capacitance can be neglected, the flow is governed by a parabolic equation; (2) more generally, if elastic ...

Prediction of Leakage Flow in a Shrouded Centrifugal Blood Pump

Artificial Organs, 2010
AbstractThis article proposes a phenomenological model to predict the leakage flow in the clearance gap of shrouded centrifugal blood pumps. A good washout in the gap clearance between the rotating impeller surfaces and volute casing is essential to avoid thrombosis. However, excessive leakage flow will result in higher fluid shear stress that may lead

Leakage effects in laminar duct flow: a numerical study

Applied Scientific Research, 1992
Summary: The influence of transverse leakage into a pressure-driven laminar flow in an infinitely long square duct is investigated. By a simple decomposition of the resulting three-dimensional pressure field, the leakage-induced secondary flow problem decouples from the primary flow problem.

Tip Leakage Flow Characteristics Downstream of an Axial Flow Fan

Volume 1: Turbomachinery, 1996
The three-dimensional viscous flow characteristics and the complex vortex system downstream of the rotor of an industrial exial fan have been determined by an experimental investigation using hot-wire anemometer. Single-wire slanted and straight type probes have been rotated about the probe axis using a computer controlled stepper motor.
