Abstract
Time-dependent cloud cavitation around the 2-D Clark-Y hydrofoil was
investigated in this paper based on an improved filter based model and a
density correction method. The filter-scale in filter based model simulation
was discussed and validated according to the grid size. Numerical results
show that in the transition from sheet cavitation to cloud cavitation, the
sheet cavity grows slowly to the maximum length during the re-entrant jet
develops. The mild shedding bubble cluster convects downwards the hydrofoil
and continues to grow up after detaching from the suction surface of
hydrofoil, and a bubble cluster introduced at the rear part of hydrofoil.
While the sheet cavity generates, the bubble cluster breakups.
