Regimes of direct contact condensation of steam injected into water

Direct contact condensation of steam injected into water is a special mode of condensation where condensation occurs on the interface between steam and water. Crucial in the modelling of direct contact condensation is the behaviour of the injected steam, commonly termed as a regime. Depending on the environmental conditions, steam injected into water appears in different regimes. These are observed in different geometrical appearances of the injected steam and are ranging from steam being condensed in the injector to bubbles and jets of steam formed in water.
