Özet

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 Re-theta approximate to 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.
