International Journal of Rotating Machinery, 2013 This paper explores the effect of inlet shear flow on the tip leakage flow in an axial flow compressor cascade. A flow with a high shear rate is generated in the test section of an open circuit cascade wind tunnel by using a combination of screens with a

Brush seal contact force theory and correlation with tests
Alexandria Engineering Journal, 2022 Brush seals are leakage performance systems that are operating against turbine shafts and bucket tips. Flexible bristle structure can compensate the rotor interference during transients, which enables closer clearance control in turbine and turbo-engine ...

Blade scale effects of tip leakage [PDF]
, 1990 October 1990Includes bibliographical references (leaves 43-44)The effects of blade-tip leakage in a turbine are investigated by modeling the stage as an incomplete actuator disk. It is found that the spanwise flow redistribution due to the gap is such as

Influence of an Argon/Silane Atmosphere on the Temperature of a Thermal Plasma
Advanced Engineering Materials, EarlyView.The influence of a silane‐doped argon atmosphere on the chemical composition and temperature of a thermal nontransferring argon plasma is investigated using optical emission spectroscopy. As a result of the high amount of free electrons resulting from the stepwise ionization and dissociation of the silane molecule, even a silane addition of 0.01 vol ...

Calculation of the Energy Loss for Tip Leakage Flow in Turbines
Chinese Journal of Aeronautics, 2004 AbstractA commercial N-S solver has been employed for simulation and investigation of the unsteady flow field inside the tip clearance of a turbine rotor. The main objective of this paper is to introduce a new method of energy loss calculation for the flow field in tip clearance region of a turbine rotor blade This method can be easily used in all ...

Contribution to tip leakage loss modeling in radial turbines based on 3D flow analysis and 1D characterization [PDF]
International Journal of Heat and Fluid Flow, 2019 [EN] The characterization of tip leakage flow plays an important role for one-dimesional loss modeling and design in radial turbine research. Tip leakage losses can be expressed as function of fluid momentum and mass flow passing through the tip gap.
