Simulations via computational fluid dynamics (CFD) have offered various insights into the flow physics of rotational aerodynamics.
However, CFD over such flows is not a straight-forward case.
While the computations of direct numerical simulations (DNS) are highly sought after, they are not realistically feasible due to the high computational overheads.
