Abstract:

We introduce foamlib, an open-source Python library developed for the purpose of interacting with OpenFOAM. foamlib provides an object-oriented interface for pre-processing, executing, and post-processing OpenFOAM cases, with capabilities for accessing and editing their related files. foamlib is mainly targeted towards testing and optimization runs, which commonly require executing a large number of different cases and analyzing their results programmatically. It has the capability to autodetect the steps needed to run a case, and will automatically arrange tasks so that multiple cases can run

Abstract:

While testing is increasingly recognized as essential in scientific software development, it is not yet standard practice within the OpenFOAM community for developing new solvers and features. This gap stems partly from the challenges of integrating testing into typical OpenFOAM workflows and limited guidance on implementing effective tests. Writing tests for complex software like OpenFOAM based projects presents unique obstacles, including difficulty in configuring tests for various cases. This paper addresses these issues by discussing established test types in the context of OpenFOAM, ident

Abstract:

Multi-physics simulations, such as conjugate heat transfer or fluid-structure interaction, are often constructed completely in OpenFOAM. However, they can also be formed by coupling OpenFOAM to third-party simulation software via a coupling tool. This approach indirectly adds to the capabilities of OpenFOAM those of other simulation tools (such as physical models or discretization methods more fitting for specific applications), and allows building complex multi-physics simulations by connecting specialized single-physics codes.

Abstract. The flow solvers OpenFOAM and EllipSys3D are compared in the case of neutral atmospheric flow over terrain using the test cases of Askervein and Bolund hills. Both solvers are run using the steady-state Reynolds-averaged Navier–Stokes k–ϵ turbulence model. One of the main modeling differences between the two solvers is the wall-function approach. The OpenFOAM v.1.7.1 uses a Nikuradse's sand roughness model, while EllipSys3D uses a model based on the atmospheric roughness length. It is found that Nikuradse's model introduces an error dependent on the near-wall cell height. To mitigate

Abstract The aim of this study is to investigate OpenFOAM using isotropic TGV flows. The main focus is on the establishment of energy conservation laws, in particular using inviscid fields to assess energy constancy; Large-Eddy Simulation (LES) is applied and the results are compared with those obtained using spectral methods; unlike previous studies of OpenFOAM, this study uses an unsteady turbulent TGV flow.

Abstract This study investigates the conservation error of kinetic energy with respect to time increment using OpenFOAM LES. The energy conservation error is verified using an inviscid Taylor-Green vortex and the effect on energy conservation is checked by varying the time increment by a factor of 30. Differences in the response of turbulent energy conservation between large and small time increments are also verified. Higher order accuracy for time increments is expected when the kinetic energy conservation accuracy is high, however the actual behaviour in OpenFOAM needs to be investigated: a

Abstract:

Channels with periodically repeating geometries are often simulated using periodic or cyclic boundary conditions. By calculating the temperature and flow field in one periodic module, the resulting distributions can be generalized to multiple modules. This reduces the computational load by simulating a single module versus the whole structure. This is a particularly useful approach when performing large optimisation studies of periodic geometries, such as compact heat exchangers. Currently, OpenFOAM only supports cyclic boundary conditions for pressure and momentum, but not heat transfer. The

Abstract:

Abstract The paper reveals the features of developing an application for conversion of computational meshes built in OpenFOAM to the msh format applied for numerical simulation of continuum mechanics (CM) problems with the ANSYS FLUENT platform. Some companies apply this platform in parallel with OpenFOAM that requires a mesh conversion module. Although there are program tools capable to solve this problem, their application involves some difficulties, mainly the necessity to pay for a license, absence of complete documentation, paid technical support. Thus, the described problem is actual and

Abstract:

Advancing the modeling of evaporation and salt precipitation is essential in CO2 storage processes in aquifers. OpenFOAM provides a platform for computational fluid dynamics (CFD) modeling with its open-source C++ object-oriented architecture that can especially be used in the development of fluid flow models in porous media. Some OpenFOAM packages have been developed in this area, and their codes are available for use. Despite this, the existing OpenFOAM literature does not include a model that incorporates multicomponent interactions in multi-phase flow systems, referred to as compositional

Abstract:

A special program module was added to OpenFoam more than 10 years ago, and a large number of studies have been devoted to its use for solving turbine engineering problems. Modeling inaccuracies can occur when the velocity is increased to supersonic flow. The aim of this work is to validate the OpenFoam open library of hydraulic turbines for the a high-pressure centrifugal compressor flow calculation and finding the parameters and calculation model that are optimal in terms of efficiency and total/total pressure ratio. For the numerical calculation, we used Reynolds averaging of the Navier-Stok

Abstract:

In this work, the explicit boundary-condition-enforced immersed boundary method (EIBM) and the lattice Boltzmann flux solver (LBFS) are integrated into OpenFOAM to efficiently solve incompressible flows with complex geometries and moving boundaries. The EIBM applies the explicit technique to greatly improve the computational efficiency of the original boundary-condition-enforced immersed boundary method. In addition, the improved EIBM inherits the accurate interpretation of the no-slip boundary condition and the simple implementation from the original one. The LBFS uses the finite volume metho

Abstract:

Machine learning based on neural networks facilitates data-driven techniques for handling large amounts of data, either obtained through experiments or simulations at multiple spatio-temporal scales, thereby finding the hidden patterns underlying these data and promoting efficient research methods. The main purpose of this paper is to extend the capabilities of a new solver called realFluidReactingNNFoam, under development at the University of Perugia, in OpenFOAM with a neural network algorithm for replacing complex real-fluid thermophysical property evaluations, using the approach of couplin
