Experimental investigation of the flow pattern for the ventilated partial cavitating flows

摘要：

　　The objective of this paper is to investigate the flow pattern of the ventilated cavitation with the experimental methods.The experiments are conducted in a closed-loop cavitation tunnel, and the flow pattern is recorded with the high speed camera.Firstly,flow pattern map is constructed to depict the flow pattern and structures, i.e.the range of Fr and CQs.As shown in the flow pattern map, four relatively stable states of a ventilated cavity could be observed, which include three partial cavity, namely continuous transparent and asymmetric cavity (CTAC), bubbly cavity (BC), continuous transparent and bubbly cavity (CTBC), and a super cavity (SC).In addition, three unstable flow pattern are also observed, i.e., foamy cavity (FC), continuous transparent and foamy cavity (CTFC), and hybrid continuous transparent and foamy cavity (CFC).
