Tip Leakage Flow in Axial Compressors [PDF]

Journal 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

Piston ring assembly for a new natural gas vehicle symmetrical multistage wobble-plate compressor [PDF]

, 2006
Natural gas is an alternative fuel of choice in the market today due to the increase in the price of petroleum, as well as out of environmental concerns. Pressure requirement for a natural gas vehicle (NGV) storage tank is 3000 psig (206 bars).

The New Performance Calculation Method of Fouled Axial Flow Compressor

The Scientific World Journal, 2014
Fouling is the most important performance degradation factor, so it is necessary to accurately predict the effect of fouling on engine performance. In the previous research, it is very difficult to accurately model the fouled axial flow compressor.

Three-Dimensional Separations in Axial Compressors [PDF]

Journal of Turbomachinery, 2004
Abstract Flow separations in the corner regions of blade passages are common. The separations are three dimensional and have quite different properties from the two-dimensional separations that are considered in elementary courses of fluid mechanics. In particular, the consequences for the flow may be less severe than the two-dimensional
