THE EFFECT OF SURFACE CURVATURE ON UNDEX-INDUCED HULL CAVITATION
Keyword(s):
Hull cavitation evolution induced by an underwater explosion (UNDEX) near a deformable steel structure is numerically investigated using a multiphase compressible fluid solver1-3 coupled with an unsteady one-fluid cavitation model4,5. A series of computations are conducted with varying structure surface curvature. Results suggest that structure surface curvature influence the peak pressures generated from the shock impact and cavitation collapse; a concave-designed surface not only causes local shock focus but also enhances the subsequent cavitation reload.
