Abstract

The paper explores a set of simple boundary conditions that can represent the flow emanating from zero-net mass-flux (ZNMF) jets in grazing flow. Results from numerical simulations of ZNMF jets in grazing flows are used to determine the key characteristics of the jet profile, and these are used to construct a series of boundary condition models. These various boundary conditions are then tested for a jet exhausting in an attached boundary layer as well as a boundary layer with an induced separation bubble.
