使用尾流振荡器的VIV和WIO。2D响应与实验的比较

VIV and WIO using wake oscillator. Comparison on 2D response with experiments

David Cebron, Benoît Gaurier, Germain Grégory

摘要:

实验结果被用来验证一个二维唯象模型的近尾流的基础上Van Der Pol尾流振荡器,这是第一个描述了二维运动的圆柱在其横向平面。在单个圆柱体的情况下,实验和数值计算结果是在相对较好的协议。这些初步结果表明,该模型可以作为一个简单的计算工具,在预测的二维涡激振动效应。

英文摘要:

Experimental results are used to validate a 2D phenomenological model of the near wake based on Van Der Pol wake oscillators, which is the first one which describes the 2D motion of a cylinder in its transversal plan. In the case of a single cylinder, experimental and numerical results are in relatively good agreement. Those first results show that the proposed model can be used as a simple computation tool in the prediction of 2D VIV effects.
