EXPERIMENTS AND COMPUTATIONS ON LARGE TIP CLEARANCE EFFECTS IN A LINEAR CASCADE

Abstract:

Large tip clearances typically in the region of six percent exist in the high pressure stages of compressors of industrial gas turbines. Due to the relatively short annulus height and significant blockage, the tip clearance flow accounts for the largest proportion of loss in the HP. Therefore increasing the understanding of such flows will allow for improvements in design of such compressors, increasing efficiency, stability and the operating range. Experimental and computational techniques h...
