IDDES is performed to investigate the effect of varying heights of cylinder on the turret at transonic Mach number Ma=0.7. Five levels of height are discussed, ranging from 0 to R. Mean and statistical results are used to compare the effect of the cylinder height. POD and DMD are performed on flow data to further investigate the spatial and temporal characteristics of dominant unsteady modes.
