Hydrodynamic Integrated Optimization of Two-D Hydrofoil Based on Kriging Model

Abstract:

Abstract. It is accurate to use CFD hydrodynamic model in optimal design, but its efficiency is low. According to variables design of experiment was arranged, then kriging model was established to by CFD hydrodynamic calculations of two-D hydrofoil. The two objectives which were the maximal ration of lift to resistance and minimal min-pressure coefficient were linearly weighted sum to a single objective. Genetic algorithm was carried out to solve the hydrodynamic performances optimization of the hydrofoil. After optimization, the ration of lift to resistance was improved and min-pressure coefficient was increased. The result shows that the Kriging model can reflect the identity of the objective, effectively reduce the cost of CFD simulation.
