Abstract

Effects of solid grains with different concentrations on cavitation evolution around NACA0015 hydrofoil were investigated. The concentrations were 5%, 10%, and 20%. Variations of averaged lift and drag coefficients and lift-drag ratio under all concentration conditions were analyzed; corresponding evolution processes of cavitation bubbles were discussed. Results indicated that with the growing of the concentration, averaged lift coefficient decreased, averaged drag coefficient increased, and lift-drag ratio reduced. They were less than their counterparts in pure water cavitation flow. Cavitation bubble evolution process and distribution of streamlines were various under the effects of the concentration. With the growing of the concentration, shedding dominant frequency and Strouhal number decreased.
