Turbulent two-phase flows are often found in industry and nature. Examples include particle-laden plumes and jets of volcanic eruptions, bubble fountains observed when filling a liquid reservoir, and the transport of contaminants through buildings. The objective of this study is to investigate the transport of bubbles and particles in multiphase fountains (flows where the buoyancy flux at the source is in a direction that opposes the momentum flux) with a particular focus on the maximum height/depth reached by such flows. The investigation includes experimental studies and simple models of multiphase fountains in confined and unconfined spaces.
