Abstract
This paper presents the results of a study of an adverse pressure gradient turbulent boundary layer (APG-TBL) at the verge of separation and a zero pressure gradient TBL (ZPG-TBL) developing on a flat surface from the same mean inflow conditions using the TBL direct numerical simulation (DNS) code of Simens et al. (J Comput Phys 228:4128–4231, 2009) and Borrell et al. (Comput Fluids 80:37–43, 2013). The APG-TBL DNS uses a modified wall-normal far-field APG boundary condition to yield the self-similar APG-TBL. The maximum Reynolds number based on momentum thickness in the present APG-TBL DNS is Reδ2=6700. The results are compared in the light of a self-similar analysis of the mean boundary layer equations.
