Abstract

Statistics from the direct numerical simulation (DNS) of an adverse pressure gradient (APG) turbulent boundary layer (TBL) are presented. Flow simulations are performed using a TBL DNS code with the desired APG applied via a tailored farfield boundary condition. The APG TBL has a maximum momentum thickness based Reynolds number (Reδ2)of6000, and a near constant ratio of pressure velocity to freestream velocity, over a range of Reδ2 from 3000 to 5000. Streamwise velocity variance profiles are shown to collapse under outer velocity scaling as opposed to friction velocity scaling over this range.
