Model concepts for multi-component processes with phase transitions

Department of Hydromechanics and Modelling of Hydrosystems

Main research subject of Holger Class

A multitude of different applications is characterized by multi-component processes, where one or multiple fluid phases are composed of several components. Often, and for very different reasons, there are phase changes observed, e.g. due to evaporation and condensation, chemical and biological reaction processes, dissolution or precipitation. Phase change can occur from one fluid phase to another, but also between fluids and solids. Commonly, this is comes along with different kinds of interaction with the flow field: for example, when carbon dioxide dissolves into water it increases the water density and may trigger a convective flow, or when permeability and mechanical rock properties are altered due to a precipitation of calcite as a solid that re-shapes the pore space.
