Query: Effect of Cavitating-bubble Generators on the Dynamics of Unsteady Cloud
  Cavitation   The present paper is devoted to the 3D numerical study of unsteady cloud
cavitation around the CAV2003 benchmark hydrofoil using a passive cavitation
controller method called cavitation-bubble generator (CGs). We investigate this
passive controller on the hydrofoil surface to affect the whole processes of
vaporization, bubble generation and bubble implosion. Firstly we simulate the
unsteady cavitating flow around the hydrofoil without CGs using a Partially-
averaged Navier Stokes (PANS) method. The turbulence approach is coupled with a
mass transfer model which implements to an open source finite-volume package.
Then we tested different sizes and angles of CGs on the hydrofoil surface. The
results of an appropriate design of the CGs shows a significant decrease of the
maximum length of the attached cavity and a large decrease of wall-pressure
fluctuation intensity on the hydrofoil surface.
