General information

The class defined in this repository can be used in openFOAM, a c++ based CFD opensource software. Visit https://www.openfoam.com/ for installation files and support.

Carreau-Yasuda model - implementation into openFOAM source code

CarreauYasuda.C
CarreauYasuda.H

This class defines the newly implemented Carreau-Yasuda shear-thinning model.

Both these files must be copied to the location:
$FOAM_SRC/transportModels/incompressible/viscosityModels

Newtonian model - implementation into openFOAM source code

Newtonian.C
Newtonian.H

This class defines a linear viscosity model .

Both these files must be copied to the location:
$FOAM_SRC/transportModels/incompressible/viscosityModels

Abstract base class for viscosity - implementation into openFOAM source code

viscosityModel.C
viscosityModel.H

This is an abstract base class gets inherited by both CarreauYasuda and Newtonian. The class defines the shear rate on any cell in the computational grid.

Both these files must be copied to the location:
$FOAM_SRC/transportModels/incompressible/viscosityModels

Defining dictionary file for constants in the Carreau-Yasuda model

transportProperties

This dictionary file like all other dictionary files must be must be present in the constants folder from where the simulation is run.

Other Dictionary Files

All other dictionary files must be must be present in the constants folder from where the simulation is run. They control important parameters such as boundary conditions, solver methods, descretization schemes, meshing method, simulation time and parallel computing.
