Abstract:
To investigate small scale turbulent structures and their statistical properties in non-isotropic turbulent flow subjected to favorable and adverse pressure gradients, a novel method to divide the instantaneous flow field into strictly monotonic elements is applied to tomographic particle-image velocimetry data. Especially the scaling regimes of velocity differences within each element with respect to their lengths are considered.
