Stability and Dynamics of Flow in a Turbulent Boundary Layer Separation Region
Result description
Separation of the turbulent boundary layer on a flat plate under adverse pressure gradient was studied experimentally using Time-Resolved PIV technique. The results of spatio-temporal analysis of flow-field in the separation zone are presented. Special attention is paid to dynamical effects. For this purpose, the POD (Proper Orthogonal Decomposition) and its extension BOD (Bi-Orthogonal Decomposition) techniques are applied as well as dynamical approach based on POPs (Principal Oscillation Patterns) method. Links to absolute instability theory of a boundary layer are indicated.
