Scale-by-scale turbulence energy in non-homogeneous turbulence
A theory of non-homogeneous turbulence is developed and applied to boundary-free shear flows. The theory introduces assumptions of (...)

Turbulent disperse two-phase flows: simulations and data-driven modeling
Many natural and industrial processes involve the flow of solid particles or liquid droplets whose dynamical evolution (...)

Ultimate Rayleigh-Bénard and Taylor-Couette turbulence
Rayleigh-Bénard flow - the flow in a box heated from below and cooled from above - and Taylor-Couette flow - the flow between two coaxial (...)

Geoinspired bioreactors: from Earth’s precession to stem cell production
Inspired by the precession of the Earth, a new bladeless mixer has been designed, which consists of a tilted and rotating (...)

Flow patterns and machine learning and to develop predictive reduced order models
Modeling turbulent flows and solving the engineering problem mentioned, is a highly complex task that requires (...)

Turbulent rotating Rayleigh-Benard convection: the geostropic regime
Most geo- and astrophysical flows are driven by strong thermal forcing and affected by high rotation rates. In these systems, (...)
