摘要： 为了研究T型水翼升力性能随浸没深度的变动规律，首先针对一组T型钢质水翼开展了水池拖曳试验，获取了36个工况的水翼升力试验数据。以此为基础验证了计算流体动力学（CFD）数值模拟方案的可行性，获取了另外36个工况的水翼升力计算数据。基于试验数据和CFD计算数据的混合数据集，对Buckle-Vellinga模型的准确性和完整性进行了验证与分析，并据此提出了修正模型。修正模型调整了近自由液面区域与远离自由液面区域的分界点深度，计算结果与混合数据集的最大偏差不超过7%，更加准确完整地描述了T型水翼升力随浸没深度的变动规律。

Abstract: To investigate the variation of T-foil lift performance with the submergence depth, the towing experiments were conducted on a group of T-foil steel models, obtaining the lift data for 36 test conditions. The CFD simulation was validated using the experimental data, and the lift data for additional 36 conditions were obtained through CFD simulations. Based on the hybrid dataset combining experimental and CFD results, the accuracy and completeness of the Buckle-Vellinga model were verified and analyzed, leading to the development of a revised model. The new model adjusts the depth of the separation point between the near free surface region and far from free surface region, with the maximum deviation between the model results and the hybrid dataset less than 7%. The revised model could describe the variation of T-foil lift with submergence depth much more accurately and comprehensively.
