title = "Capability of RANS Simulations to Reproduce Flat Plate Boundary Layer Interaction with Suction and Oscillatory Blowing",
abstract = "Simulations of near zero pressure gradient turbulent boundary layer interacting with Suction and Oscillatory Blowing (SaOB) were conducted using URANS equations. Different blowing velocity Boundary Conditions (BC) and spatial resolutions were investigated with the effort to reproduce the hot-wire measurements on the flat plate and thus pave the way for application on realistic configurations. Time-resolved BCs acquired from bench-top tests were compared with idealistic constant velocity BCs regarding their interaction with external boundary layer flow. URANS simulations were able to reproduce the measurements in a qualitative manner provided that measured boundary conditions were applied. Constant velocity BCs led to an optimistic prediction in terms of boundary layer energizing, as they neglected the non-uniformity of the blowing jet and even more importantly the remaining mass flow leaving the inactive nozzle. Mesh resolution had a significant impact on the propagation of the stable counter-rotating streamwise vortices emanating from each suction hole that is part of the SaOB actuator.",
