説明
A time-spectral, or reduced-frequency method for the CFD is developed in place of a time-marching method for simulations of periodically unsteady flows around oscillating bodies. The efficiencies and accuracies of the method are validated through comparisons with transonic-flow experiments for two- and three-dimensional wings. For the case of a three-dimensional viscous flow, the computation time to obtain the same periodic flow with a time-marching solution of a sufficiently fine time step was about 1/18 in the time-spectral method. The method is expected for applications to calculating dynamic derivatives of aircrafts or wing-flutter problem where the flow responses to small-amplitude oscillations are used to judge the stability.
