Nihon Kikai Gakkai ronbunshu, 2016 A tip leakage flow is well known to have predominant influence on a loss generation in a compressor. An impeller for a transonic centrifugal compressor is generally composed of the main and the splitter blades to gain the choke flow rate.

Measurement and Prediction of Tip Leakage Losses in an Axial-Flow Transonic Turbine [PDF]
Volume 1: Aircraft Engine; Marine; Turbomachinery; Microturbines and Small Turbomachinery, 1997 This paper presents a simple method for predicting tip leakage losses in transonic axial-flow turbines. The method is based upon experimental work conducted on a flat plate at 5° incidence and with isentropic exit Mach number of 1.26. The tip gap height was varied from zero up to 15% of chord.

Effect of tip winglet position on tip flow and noise of axial flow fan
Heliyon, 2023 In order to investigate the impact of blade tip winglet position on the internal flow and noise characteristics of axial flow fans,three different blade tip winglets,namely the TSW blade, the SSW blade, and the PSW blade,were hereby proposed.

Experimental analysis and modeling of the losses in the tip leakage flow of an isolated, non-rotating blade setup [PDF]
Experiments in Fluids, 2020 Improving pressure rise capabilities of axial compressors requires an in-depth understanding of the losses produced in the tip leakage region. Here, a generic setup that magnifies the tip region of an isolated, non-rotating blade is used with the objectives of describing the main flow components and evaluating the related sources of loss.

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

Numerical investigation of tip clearance effects on the performance of ducted propeller
International Journal of Naval Architecture and Ocean Engineering, 2015 Tip clearance loss is a limitation of the improvement of turbomachine performance. Previous studies show the Tip clearance loss is generated by the leakage flow through the tip clearance, and is roughly linearly proportional to the gap size.
