Temperature development in the leakage flow of screw extruders [PDF]
, 1978 Temperature distribution at the exit of the leakage gap is of interest for a number of problems. For the calculation of temperatures, the leakage flow may be considered to be a pure drag flow to a good approximation.

Effect of internal leakage on torque converter characteristics
Advances in Mechanical Engineering, 2020 To understand the effect of internal leakage on the torque field and characteristics of a torque converter (TC), a transient analysis was performed on the internal flow of a TC and the pressure pulsation characteristics of monitoring points in the ...

Fluid Flow Equations for Rotordynamic Flows in Seals and Leakage Paths [PDF]
, 2001 Fluid-induced rotordynamic forces produced by the fluid in an annular seal or in the leakage passage surrounding the shroud of a pump or turbine, are known to contribute substantially to the potential excitation forces acting on the rotor.

Shock Formation in Overexpanded Tip Leakage Flow [PDF]
Volume 1: Turbomachinery, 1992 Shock formation due to overexpansion of supersonic flow at the inlet to the tip clearance gap of a turbomachine has been studied. The flow was modelled on a water table using a sharp-edged rectangular channel. The flow exhibited an oblique hydraulic jump starting on the channel sidewall near the channel entrance.

Effect of Swirl on Rotordynamic Forces Caused by Front Shroud Pump Leakage [PDF]
, 2002 Unsteady forces generated by fluid flow through the impeller shroud leakage path of a centrifugal pump were investigated. The effect of leakage path inlet swirl (pump discharge swirl) on the rotordynamic forces was re-examined.

Desensitization of Tip Clearance Effects in Axial Flow Turbines
Journal of Fluid Science and Technology, 2010 The present study aims to control the leakage flow and total pressure loss in high pressure turbines. A new tip shape is proposed. It is based on the triple squealer shape by adopting a new middle squealer, along the camber line, whose first and last ...
