Abstract
Interfaces are commonly observed features of turbulent flows. Previous research has indicated the significance of these interfaces on the overall dynamics of the turbulent flow [1]. The current research focuses on both the external Turbulent/Non-Turbulent (T/NT) interface as well as internal layers that are present in an experimentally determined Turbulent Boundary Layer (TBL). Experiments are performed using planar Particle Image Velocimetry (PIV). First of all, attention is paid to the method of determining the interfaces. Furthermore, a quantitative comparison with jet data from [2] is made. Third, the properties of the internal interfaces are compared with the T/NT interface. Finally, the entrainment velocities of the interfaces are derived from the experimental results, which may be indicative of the growth rate of the TBL [1].
