High-Performance CFD Validation of GPPH Planing Hull in Calm Water

The Generic Prismatic Planing Hull (GPPH) is a representative geometry of typical planing hulls that is designed as part of an Office of Naval Research project to obtain a comprehensive set of experimental data for assessing of CFD tools. The purpose of the current work is validation studies using OpenFoam for GPPH in calm water. The Froude numbers range from 1.14 to 2.51 and the boat is free to heave and trim. The experimental data and uncertainties for resistance, heave, and trim at four different speeds were used as a CFD grand challenge at the recent MACC 2018 conference. Ten different submissions were made which included potential flow, boundary element, LBM, and URANS solvers. Herein, we present OpenFoam results and provide a comparison with the previous simulations. The simulation uncertainty intervals and the state of the art validation uncertainties are determined accounting for the experimental uncertainty and the numerical uncertainty. Simulation uncertainties include the uncertainty due to the different simulations similar to the facility bias for experiments. The current state of the art for planing hull is summarized and compared with the previous studies for conventional hulls at lower speeds. Future studies will include motions and slamming pressures in waves.
