Abstract

Abstract: The effect of boundary layer on the erosion wear cause of the pump blade is analyzed . Studies accept that wavy wear trace for blade face is a brand of the ready-ordered structure of abrupt vortex in turbulent boundary layer. Evolutional rule of wear trace wavelength and wave hollow from calculation of boundary layer parameter are deduced. A new thread of re-searches in erosion wear is provided .

Key words: Abrupt vortex, Boundary layer, Erosion wear, Wear trace
