Verification and validation for KCS total resistance

Abstract

This study presents CFD simulations of the KCS model ship, focusing on ship resistance, free-surface behavior, and predictions of sinkage and trim at a Froude number of 0.26. Reynolds-Averaged Navier-Stokes (RANS) equations are solved using the k-ω SST turbulence model. Verification and validation are carried out through a generalized Richardson Extrapolation method, following Stern et al. [1] methodology. Results are compared with experimental data for total resistance coefficient, sinkage, trim, and wave patterns.
