The effect of different similarity transformations on ensemble mean particle paths in turbulent spots
Year: 1983
Type: article
Abstract: Computations from measurements taken on the plane of symmetry of turbulent spots in a laminar boundary layer are presented here. Different types of similarity growths are compared and discussed. The streamline pattern and the instantaneous particle trajectories are weakly affected by the change of vertical growth law, providing no explanation for the apparent contradictions observed in temperature and velocity fields. This result suggests that the ensemble averaged field improperly represents the dynamics of the spot.
