Scale-adaptive simulation of unsteady cavitation around a naca66 hydrofoil [PDF]
, 2019 Distances between consecutive aftershocks are analysed by means of mono- and multifractal theory with the aim of quantifying the complexity of the physical mechanism governing them, as well as their predictability and predictive instability.
