Two different cartesian-grid methods are used to simulate the flow
around the DDG 5415. The first technique uses a "coupled level set and
volume-of-fluid" (CLS) technique to model the free surface. The
no-flux boundary condition on the hull is imposed using a finite-volume
technique. The second technique uses a level set method (LS) to model the
free surface. A body force technique is used to impose the hull
boundary condition. The predictions of both numerical techniques are
compared to whisker probe measurements of the DDG 5415. The level set
technique is also used to investigate breakup of a two-dimensional spray
sheet.
