摘　　要：为减小赛艇行驶过程中的阻力、提高运动员的成绩,对赛艇艇型进行优化。采用RNG k-ε(renormalizationgroup k-ε)湍流模型、VOF(volume of fluid)方法对单人赛艇的周围流场和阻力特性进行了数值计算,获得了赛艇周围的速度分布和压力分布等流场信息,实验结果证实了数值计算的可靠性。利用数值计算对赛艇艇型进行了优化,得到了赛艇阻力与艇型的关系。研究结果对于改善赛艇性能、减小赛艇阻力具有重要的参考价值和指导意义。The rowing boat type was optimized to reduce the rowing resistance and to help the athletes to earn a good competition outcome. RNG k-e turbulent model and VOF method were used to calculate the flow field and the resist- ance 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 be- tween resistance characteristic and rowing type was obtained. The results could give some instructions to reduce the row- ing boat resistance and improve its performance.
