Heat Transfer in Phase Change Materials with Multiple Fin Insertion
Paolo Proia, Mauro Sbragaglia, Giacomo Falcucci
We leverage 3D numerical simulations to study phase change materials (PCMs) cells under the effect of buoyancy forces. The solid PCM is heated from a source boundary, triggering me…
Heat transfer modulation in Phase Change Materials via fin insertion
Paolo Proia, Mauro Sbragaglia, Giacomo Falcucci
We leverage a large set of numerical simulations to study optimized geometrical configurations for Phase Change Materials (PCMs) cells. We consider a PCM cell as a square enclosure…
Extreme flow simulations reveal skeletal adaptations of deep-sea sponges
Giacomo Falcucci, Giorgio Amati, Pierluigi Fanelli +4
Since its discovery, the deep-sea glass sponge Euplectella aspergillum has attracted interest in its mechanical properties and beauty. Its skeletal system is composed of amorphous…
Metastable and Unstable Dynamics in multi-phase lattice Boltzmann
Matteo Lulli, Luca Biferale, Giacomo Falcucci +3
We quantitatively characterize the metastability in a multi-phase lattice Boltzmann model. The structure factor of density fluctuations is theoretically obtained and numerically ve…
