Abstract:

The rowing boat type was optimized to reduce the rowing resistance and to help the athletes to earn a good competition outcome. RNG k-ε turbulent model and VOF method were used to calculate the flow field and the resistance characteristics, and the velocity and pressure distribution around a single rowing boat was obtained. Experimental results showed the reliability of the numerical calculation. The rowing boat type was optimized and the relationship between resistance characteristic and rowing type was obtained. The results could give some instructions to reduce the rowing boat resistance and improve its performance.

Key words: turbulent model, VOF, numerical calculation, rowing, free face
