CFD-BASED OPTIMIZATION OF TANKER STERN FROM - MINIMIZATION OF DEVELOPED HORSEPOWER USING SELF-PROPULSION SIMULATOR

This paper concerns tanker stern form optimization using the CFD-based optimization method. The main focus is placed on minimization of delivered horsepower (DHP) in conjunction with application of self-propulsion simulator, which is based on extension of a Reynolds-averaged Navier-Stokes (RaNS) equation solver including propeller effects evaluated by the infinite-bladed propeller theory. The paper presents an overview of the numerical method given and discusses how the results include identification of salient differences of forms and integral parameters between for the original and optimized hull forms. In conclusion, the present method appeared to successfully optimize the given tanker stern form for minimum DHP, and the modification trends automatically demonstrated in the paper agree well with those commonly in use in traditional tanker hull form designs.
