Abstract

The centrifugal compressor is widely used in process industries, turbochargers, small gas turbine engines, etc. The inherent advantages of centrifugal compressor are high pressure ratio per stage, compactness, light weight design, low mass flow applications, reasonable efficiency, large surge margin and low cost. The present work comprises of analysis of computational study of tip clearance effects in a low speed centrifugal compressor using structured multi block grid. The flow through the centrifugal compressor is modelled in Blade Gen and solved by a CFD solving software, CFX. Standard k- turbulence model is used for obtaining the solution. Centrifugal compressor impeller with four values of clearances i.e., 0 mm, 1 mm, 2 mm and 5 mm along blade height are examined. The effect of tip clearance on total pressure from inlet to outlet of the compressor is analyzed. The drop in total pressure with increase in tip clearance is found to be high at the tip of the blade due to high pressure fluid leakage at the tip of the blade. The reduction of blade loading near the tip with tip clearance increase is observed.

OBLONG DIFFERENCE MEAN PRIME LABELING OF SOME TREE GRAPHS

Abstract

The labeling of a graph, we mean assign some integers to the vertices or edges (or both) of the graph. Here the vertices of the graph are labeled with oblong numbers and the edges are labeled with mean of the absolute difference of the end vertex values. Here the greatest common incidence number (gcin) of a vertex of degree greater than one is defined as the greatest common divisor of the labels of the incident edges. If the gcin of each vertex of degree greater than one is 1, then the graph admits oblong difference mean prime labeling. Here we characterize some tree graphs for oblong difference mean prime labeling.
