WebOct 12, 2024 · The results show that the self-excited force of the split double-box beam in vortex-induced vibration improved its spanwise correlation. Compared with those in a static state, the spanwise correlation of the lift coefficient and torque coefficient increased by 55% and 87%, respectively, and the resistance coefficient increased by more than 10 ... WebThe coefficients and lift and drag were calculated and compared at various different angles ranging from 0 o to 20 o. The results show that the tapered wing planform has higher lift coefficients and lower drag coefficients than the rectangular wing planform at all angles.
