Toolbox to simulate GNF and viscoelastic fluid flows in OpenFOAM®

About

RheoTool is an open-source toolbox based on OpenFOAM® to simulate the flow of Generalized Newtonian Fluids (GNF) and viscoelastic fluids. The library containing the viscoelastic models has been developed based on the library used by viscoelasticFluidFoam (Favero et al., 2010, J. Non-Newtonian Fluid Mech.), already present in foam-extend 3.2.

The theory behind the single-phase flow solver used in RheoTool can be found in: Pimenta F. and Alves M.A., 2017, J. Non-Newtonian Fluid Mech..

Features

• all the features are available for 2D/3D problems and generic grids;
• the code is fully-parallelized;
• wide range of viscoelastic and GNF models;
• the log-conformation tensor approach is available for all viscoelastic models;
• the transient flow solver (rheoFoam) is highly stable regarding pressure-stress-velocity coupling;
• the material functions of any model can be obtained numerically (rheoTestFoam);
• a group of tutorials is included to exemplify the application of the solvers to different problems;
• the theory and the tutorials are described in a user-guide;
• a solver for two-phase flows is available (rheoInterFoam), where any GNF or viscoelastic model can be used for each phase (in-development);
• the tool is available for both OpenFOAM® and foam-extend versions.

Installation

RheoTool can be either cloned using git via: git clone https://github.com/fppimenta/rheoTool or simply downloaded from the GitHub page at https://github.com/fppimenta/rheoTool.

The repository includes versions of RheoTool for: OpenFOAM® v2.2.2, OpenFOAM® v4.0 and foam-extend v3.2 (branch nextRelease; lastly tested on commit 6de4e26).

To install RheoTool, please follow the instructions in Chapter 2 of the user-guide.
