What drives flow unsteadiness in the shock wave/turbulent boundary layer interaction? Two mechanisms are widely recognized to play a role this problem: upstream forcing and downstream feedback. In work, through combined use of system identification, spectral decomposition, linear stability analysis, we demonstrate that feedback, driven by traveling acoustic waves, is dominant mechanism behind l...

This paper focuses on the relevant information for collecting and presenting contextual information, its effects and impact on the learning interaction cycle, and mechanisms of controlling it. The core principle of the learning interaction cycle is the interaction of learners with their learning environment. Previous research highlights that such interaction is important for the experience and ...
