Numerical evaluation of the wave pattern for fast ships with taking into account the dynamic trim and sinkage

This paper presents results of the numerical evaluation of the fast container ship's wave pattern, based on the RANSE (Reynolds-Averaged Navier Stokes Equations) method with dynamic trim and sinkage taken into account. Evaluating the ship's running attitude is based on coupling the flow solver with solving the motion equations for the ship hull. The results are presented for four speed values and contain: ship's running attitude (defined by changes of ship draught and trim angle), wave contours and wave profiles in chosen planes. The computed ship's running attitude and wave profiles are compared with the experimental results.
