为提高赛艇器材的性能,需要对赛艇的阻力特性进行研究。采用数值模拟的方法研究了赛艇的阻力性能,模拟时湍流模型采用RNG k-ε模型,自由面处理采用VOF方法,并通过与实验结果的对比证实了数值方法的有效性。研究结果表明,通过数值模拟可以较准确地预测赛艇阻力,并能捕捉赛艇周围的自由面,获得赛艇周围的流场信息。通过研究,可以为进一步优化赛艇艇型的研究奠定基础。
In order to improve the performance of rowing equipment, the drag characteristics of rowing need to be studied. The resistance performance of rowing was studied by numerical simulation. The model of RNG k-ε was adopted for the turbulence model and the VOF method for free surface treatment. The effectiveness of the numerical method was verified by comparison with the experimental results. The results show that the resistance of the rowing boat can be predicted accurately by numerical simulation and the free surface around the rowing boat can be captured and the flow field around the rowing boat can be obtained. Through research, we can lay a foundation for the further research of rowing craft.
