OpenFOAM Solvers
OpenFOAM as a very well developed, widely used and open-source CFD platform, provides a reliable environment for further developments. In most of my developments, OpenFOAM is used as the base for further development of applied CFD tools and widgets. A wide range of developments, from specific solvers for separation engineering such as membraneFoam and adsorpFoam to more generic solvers such as porousFoam and multiPhaseFoam have been developed by me. Part of my developments are released as open-source codes (check bottom) and some other are described and introduced in conference and journal publications.
Some of developments are provided here, feel free to download them and use them (By using these codes, the user acknowledges and agrees to the terms of use - see bellow). The published developments, mostly include:
- The source code for the solver
- Needed/added libraries
- Instructions to compile (if needed - in the form of Allwmake)
- Examples how to set up the case
Interested to know more about my developments or want to cooperate with me simply contact me.

adsorpFoam
Description:
adsorpFoam solver was specifically developed to handle adsorption phenomena, where heat and mass transfer occurs between gas and solid materials in multiple regions (fluid and solid). The solver applies distinct methodologies for each of the two areas; for the fluid area, it employs the Navier-Stokes equations in conjunction with the continuity equation to determine the interconnected pressure and velocity field of the fluid implicitly. Following that, heat and mass conservation equations are used explicitly to calculate the temperature and mass fractions of species within the fluid. Conversely, for the solid side, the energy conservation equation is resolved to determine the temperature field within the solid particles. Since adsorption is a surface phenomenon, no mass conservation equation is employed for the solid area. Finally, the two regions are coupled explicitly through a shared boundary condition located at the adsorption active surface.

membraneFoam
Description:
membraneFoam employs a multi-region technique to model various compartments of a membrane module, such as retentate and permeate, as separate regions. These regions are interconnected using the membrane boundary. The algorithm can manage mass and heat transfer through the membrane boundary for any number of components (species). Each region can possess its own thermo-physical properties, turbulence models, and other characteristics. The solver is designed in a modular fashion, making it relatively simple to expand the available models. The solver is highly adaptable and can be utilized in 1D or 3D membrane modeling, depending on the desired outcomes.

multiPhaseFoam
Description:
multiPhaseFoam solver is a computational tool for simulating mass transfer between phases using a volume of fluid approach (VoF) that enables the analysis of multi-component fluid systems, where mass transfer takes place between different phases. The solver employs a volume of fluid approach, which is a widely-used technique for modeling multi-phase flows. It tracks the interface between the fluid phases in every computational cell and calculates the mass transfer between them. The solver can simulate various types of mass transfer mechanisms such as diffusion, convection, and chemical reactions. It can also handle complex geometries and different boundary conditions. The solver is capable of modeling a wide range of applications, such as separation processes, mixing, and reaction engineering.

porousFoam
Description:
porousFoam is a computational tool that enables the analysis of fluid flow in porous materials. The solver is based on the Navier-Stokes equations, which are modified to account for the presence of a porous medium. The solver can handle various types of porous media, including packed beds, fibrous media, and porous membranes. The solver uses a numerical discretization method to solve the governing equations and simulate the fluid flow through the porous material. The solver can also take into account heat transfer. The solver is particularly useful for simulating fluid flow in porous media used in industrial applications such as filtration, catalysis, and thermal management.
Sample Simulation:
Features:
- Incompressible and compressible flow through porous media
- Physical velocity
- Two field energy for solid and fluid

blockCoupledFoam
Description:
The coupledMatrix is a library originally implemented to foam-extend, which I ported to OpenFOAM 2.3.0 to be used for implicit coupling of regions with common boudaries (e.g. fluid and porous regions). It uses a block-coupled approach, where different regions of the simulation domain are treated separately and then coupled implicitly together through a common boundary and a single set of equations is solved for all the regions. This library provides a modular implementation making it relatively simple to modify and extend.
As a sample application the blockCoupledFoam solver using the mentioned library was developed to implicitly couple two regions. In this development pressure and velocity fields between the two regions were coupled through a common boundary and after the discretization a single set of equations for each of the properties was solved. The solver is based on the multi-region approach with an implicit coupling in between the regions.
Sample Simulation:
Features:
- Ported coupledMatrix library from foam-extend
- coupledLduMatrix for solving coupled equations and regions
- RegionCoupling for implicit coupling of regions
- Sample solver for coupling U-p over two regions
