Natural flows

Natural flows

  • Circulation in lakes
  • Wave dynamics
  • Avalanches and debris flows
  • Granular flows
  • Dispersion of pollutants in waters

Exemplary topics

  • Development of a thermodynamic consistent model for debris flows, regarding the evolution of a dynamic pore-fluid pressure and intergranular hypoplastic frictional behavior, introduced as additional internal variables. Numerical simulations investigate the influence of the dynamic pore-fluid pressure and the intergranular friction.
  • Constitutive modeling in a symbolic computational framework: The exploitation of the entropy principle in its formulation by Müller and Liu is facilitated with the aid of symbolic computation.

The objective of the project is to investigate the thermodynamic behavior of electrolyte solutions whose constituents react to form solids. Particularly, we are interested in modeling the thermodynamic behavior of calcium carbonate supersaturated solutions. For this purpose, we perform numerical simulations in commercial fluid dynamics softwares and compare the results with experimental information.
