The influence of steady blowing and roughness on transitional separated boundary layers etc15 Tracking Number 287Presentation: Session: Control 2 Room: Room D Session start: 15:00 Tue 25 Aug 2015 Mark Phil Simens mark@torroja.dmt.upm.es Affifliation: Ayse Gungor ayse.gungor@itu.edu.tr Affifliation: Topics: - Control of turbulent flows, - Instability and transition, - Wall bounded flows Abstract: This paper presents the results of a study between two types of forcing, namely steady blowing and a tripwire, on the control of laminar separated boundary layers. The analysis focuses on the differences in the transition process between these two types of forcing. This effect will be studied using direct numerical simulation. The main differences consists in the coherent structures formed during transition and the overall kinetic energy growth. |
