Free surface CFD simulations of the flow around a planing plate
Free surface CFD simulations of the flow around a planing plate
A RANS ((Reynolds Averaged Navier Stokes)) free surface flow solver has been used to model the flow around a 2-D planing plate ((Fn = 1.596)). Calculations have been made for both the plate planing at the free surface and with the free surface approximated as a slip wall of prescribed form. Results for the lift force generated by the plate are presented and compared for the two methods. The results of the approximated free surface are found to be closer to empirical equations for flat plate lift than those where the free surface has been calculated. The work demonstrates the difficulties of accurately capturing a known flow using a volume of fluid ((VOF)) approach. However future enhancements should offer the ability to use such calculations for design.

Abstract
A RANS ((Reynolds Averaged Navier Stokes)) free surface flow solver has been used to model the flow around a 2-D planing plate ((Fn = 1.596)). Calculations have been made for both the plate planing at the free surface and with the free surface approximated as a slip wall of prescribed form. Results for the lift force generated by the plate are presented and compared for the two methods. The results of the approximated free surface are found to be closer to empirical equations for flat plate lift than those where the free surface has been calculated. The work demonstrates the difficulties of accurately capturing a known flow using a volume of fluid ((VOF)) approach. However future enhancements should offer the ability to use such calculations for design.
