摘要
Unsteady aerodynamic lift force and pitching moment for a 2-D rectangular cross section are evaluated by the discrete vortex method. The section is in coupled oscillation for heaving/torsional 2 d.o.f. The results are discussed by comparison with the data from wind tunnel experiments and with the analytical values determined by the non-stationary thin airfoil theory (Theodorsen function). © 1993.
