摘要：

为了研究楔形体入水问题以及基于粒子图像测速(PIV)进行砰击压力间接评估的可行性,应用时间解析PIV(TR-PIV)技术对不同底升角楔形体入水过程中的流场进行测试.开展相应的数值模拟,依据PIV结果进行瞬时砰击压力重构.详细分析了入水过程中的运动响应与流场结构,探讨了基于TR-PIV压力重构方案的准确性和适用性.结果表明:楔形体入水流场的TR-PIV测试结果与数值结果吻合良好.对于不同网格间距和时间步长,压力重构方案均具有良好的精确性.基于TR-PIV重构不同底升角楔形体的砰击压力场结果与数值结果吻合良好,砰击载荷的评估结果同样吻合良好.

Abstract:

In order to study the wedge water entry problem and the feasibility of indirect evaluation of the slamming pressure based on particle image velocimetry (PIV), tests were conducted on the water entry of wedges at different deadrise angles using time-resolved PIV (TR-PIV). A numerical simulation was performed, and the transient pressure was reconstructed based on the PIV results. The motion response and flow field structure in the process of entering the water were analyzed in detail, and the accuracy and applicability of the pressure reconstruction scheme based TR-PIV were discussed. The results show that a good agreement is observed in TR-PIV measurements of the water entry and the numerical results. For different grid spacings and time steps, the pressure reconstruction scheme always has a good accuracy. The results of the slamming pressure field reconstruction of the wedges at different deadrise angles based on TR-PIV agree well with the numerical results, so do the evaluation results of the slamming load.

Key words: wedge, water entry, time-resolved PIV (TR-PIV), pressure reconstruction
