Influence of Time-Varying Freestream Conditions on the Dynamics of Unsteady Boundary-Layer Separation

What is it about?

Unsteady flow separation of a turbulent boundary layer under dynamic pressure gradients is investigated using the Large-Eddy Simulation technique. The unsteadiness is introduced by prescribing an oscillating freestream vertical velocity profile at the top boundary of the domain. The goal of this paper is to analyze the effects of several freestream forcing profiles while the oscillation frequency is kept the same for all cases.
