The Precipitation and Crystallization in Fluid Flow Interface
The Precipitation and Crystallization in Fluid Flow () multiphysics interface is used to simulate precipitation of a chemical species in a fluid solution and solve for the size distribution of the precipitate. The interface can be used for stationary and time-dependent analysis in 2D, 2D axial symmetry, and 3D.
The interface combines the Laminar Flow, the Transport of Diluted Species, and the Size-Based Population Balance interfaces.
The Precipitation in Fluid Flow multiphysics coupling is automatically added and couples the fluid flow to the species transport and a size distribution of particles. The species transport interface solves for one or multiple solute species in the reactants in a precipitation process. The population balance interface solves for the transport and size distribution of the precipitate.
On the constituent physics interfaces:
•
The Laminar Flow interface solves the Navier–Stokes equations for conservation of momentum and the continuity equation for mass conservation.
•
The Transport of Diluted Species interface solves for a variable number of species concentrations. The species equations include reactions, and transport by convection, and diffusion.
•
The Size-Based Population Balance interface solves for a discretized size-distribution used to represent the precipitate. The interface solves for the nucleation, growth, aggregation, and breakage of particles, as well as transport by convection, and diffusion.
