Research on Resistance Optimization of Multi-purpose Vessel Wind Based on Numerical Simulation

The paper presents a numerical simulation method on the wind resistance optimization of the 19000 t multi-purpose vessel. Firstly, the paper numerically simulates wind-against resistance of ship hull and superstructure. Then, it qualitatively analyzes wind resistance pressure distribution, and designs a wind resistance reduction structure. At last, it presents a numerical simulation based the optimization method of computing best optimal wind resistance structure.
