A finite volume-based solver with rigid moving mesh and delayed detached eddy simulation (DDES) techniques is implemented to investigate the unsteady flows around an 80°/65° double-delta wing (DDW) subjected to sinusoidal pitching motions. The focus concentrates on understanding the behaviour of the...
