DISCUSSION ON RELATION BETWEEN BOUNDARY LAYER AND WALL EROSION CAUSED BY STRIKING OF PARTICLES

The kinetic characteristics of particles moving through laminar or turbulent boundary layer are computed anddifferent erosive situations caused by striking of particles are compared. The function of anti-erosion sinews addedon the blades is analysed. The energy detrition in the two-phase turbulent flow is discussed. The content is helpfulto the design of anti-erosion fans.
