The axial tip clearance leakage analysis of the squealer blade tip for the liquid-ring pump [PDF]

open access: yesScientific Reports
The gas-liquid two phase leakage flow in the clearance of Liquid ring pump has severe negative impact on its hydraulic performance. In order to analyze the flow structure of leakage flow and suppress it, the squealer blade tip was introduced to Liquid ...

Investigation of Flow through a Labyrinth Seal [PDF]

open access: yesINCAS Bulletin, 2021
Growing performance requirements for gas turbines have led to a continuous increase in gas temperature and pressure ratios. Together with the resulting increase in cooling flows, this requires more and more minimization and control of internal gas leaks.

Accuracy Investigations of Dynamic Characteristic Predictions of Tip Leakage Flow Using Detached Eddy Simulation

open access: yesAerospace, 2023
The accurate prediction of tip leakage flow is the premise for flow mechanism analysis and compressor performance optimization. The detached eddy simulation (DES) method, which compromises cost and accuracy, has excellent potential for a high Reynolds ...

Effect of an Axially Offset Impeller on the Transient Physics of Asymmetric Flow in a Double-suction Centrifugal Fan [PDF]

open access: yesJournal of Applied Fluid Mechanics
The impeller of a double-suction centrifugal fan may be subject to axial offset due to assembly or operational failure. The internal flow is asymmetric about the central disc and deteriorates the fan’s performance.

Impact of Leakage Inlet Swirl Angle in a Rotor–Stator Cavity on Flow Pattern, Radial Pressure Distribution and Frictional Torque in a Wide Circumferential Reynolds Number Range

open access: yesInternational Journal of Turbomachinery, Propulsion and Power, 2020
In the side-chambers of radial turbomachinery, which are rotor–stator cavities, complex flow patterns develop that contribute substantially to axial thrust on the shaft and frictional torque on the rotor.

Tip Leakage Flow in Axial Compressors [PDF]

open access: yesJournal of Turbomachinery, 1990
Experimental measurements in a linear cascade with tip clearance are complemented by numerical solutions of the three-dimensional Navier–Stokes equations in an investigation of tip leakage flow. Measurements reveal that the clearance flow, which separates near the entry of the tip gap, remains unattached for the majority of the blade chord when the tip
