英文摘要 | Vortex-induced vibrations (VIVs) of a fixed two-dimensional perimeter-reinforced (PR) membrane wing at Re (Reynolds number) 1000 and (angle of attack) 30 are investigated using fluid-structure interaction simulations. By employing very fine increments for Re and , bifurcation boundaries of the dynamic response of the membrane wing in the Re- plane are captured. With increase in Re and/or , it is found that the VIV state of a fixed PR membrane wing will change progressively from static state to period 1 via a Hopf bifurcation and then from period 1 to multiple period and chaos via a succession of period-doubling bifurcations. The Hopf bifurcation is triggered by the shedding of the leading- and/or trailing-edge vortices, while the period-doubling bifurcations are induced by the appearance and evolution of the secondary vortices on the upper surface of the membrane wing at higher Re and . With an increase in the structure rigidity or pre-strain, the overall responses of the membrane wing are not changed much in the Re- plane except that the period 1 response near and is destroyed, due to the significant change of the shedding process of the leading-edge vortices. Moreover, it is also found that unsteady responses of the PR membrane wing at can be suppressed by small pre-strain. |
