AB - 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.
