DIRECT NUMERICAL SIMULATION OF A SELF-SIMILAR ADVERSE PRESSURE GRADIENT TURBULENT BOUNDARY LAYER

The statistical scaling properties of a self-similar ad-verse pressure gradient (APG) turbulent boundary layer (TBL) are presented. The intended flow is generated us-ing the direct numerical simulation (DNS) TBL code of Simens et al. (2009) and Borrell et al. (2013), with a mod-ified farfield boundary condition (BC). The conditions for self-similarity and appropriate scaling are derived, with mean and Reynolds stress profiles presented using this scal-ing. The APG and ZPG DNS are also compared under the classical viscous scaling
