Abstract

Details are provided on the development of a farfield boundary condition for the direct numerical simulation of an adverse pressure gradient (APG) turbulent boundary layer (TBL) at the verge of separation. The APG TBL achieves a region constant pressure velocity to freestream velocity ratio over a momentum thickness based Reynolds number range of R≈ 2000 to 6000. Mean velocity deficit and Reynolds stress profiles are presented under both friction velocity and pressure velocity based scaling within this range. The pressure velocity scaling demonstrates a collapse of the statistical profiles.
