4D simulation of explosive eruption dynamics at Vesuvius

Three-dimensional simulation of a partial column collapse scenario at Vesuvius. The input conditions of the multiphase flow model are representative of a Sub-Plinian eruption with a mass flow rate of 8 x 10’7 kg/s. Two particle classes of 30 and 500 microns were modeled to represent the ejected pyroclasts. The…
