摘　　要：该文针对T型水翼升阻力简化算法在不同尺度与速度下的适用效果开展研究。计算结果表明:当雷诺数的量级为10~5时,简化算法与计算流体力学(computational fluid dynamics,CFD)数值计算结果的吻合度较高,具有较好的适用性;当雷诺数的量级从10~5提高到10~6时,简化算法的升力部分仍然适用,但阻力部分与CFD计算结果的偏差明显加大,已无法保证适用性。上述计算结果也部分得到了拖曳试验结果的验证,目前的T型水翼升阻力简化算法亟需进一步更新与完善。The applicability of a simplified algorithm for estimating T-foil lift and drag at different scales and speeds is studied.The calculation results indicate that when the Reynolds number Re is on the order of 105,the simplified algorithm has a high degree of agreement with the CFD numerical calculation results and has good 5 applicability.When the Reynolds number Re increases from 10 to 106,the lift part of the simplified algorithm still applies,but the deviation between the drag part and the CFD results significantly increases,making it unable to guarantee applicability.The above calculation results have also been partially validated by the drag test results,and the current simplified algorithm for estimating lift and drag of T-foils urgently needs further updates and improvements.
