dc.description.abstractenModern requirements for development and modernization of equipment and processes are speed, accuracy, minimum costs. Usage of numerical simulation with latest achievements in computer hardware and software can provide these requirements at the appropriate level. Numerical modeling allows one to quickly analyze new solutions and find the most effective ones. Also it can be apply for finding optimal value of input parameters or best process conditions. Computational simulation allows one to look deeper into physical phenomena or technological processes. And it can determine the values that are difficult or impossible measured with experiment. Nowadays computer simulation has become a useful part of modeling many natural systems in physics, chemistry and biology as well as in engineering to gain insight into the operation of those systems. A lot of different softwares are used for purpose of numerical modeling. OpenFOAM is a good example of this class of software. OpenFOAM (Open Source Field Operation and Manipulation) is a C++ toolbox for the development of customized numerical solvers, and pre-/post-processing utilities for the solution of continuum mechanics problems, including computational fluid dynamics (CFD). The code is released as free and open source software under the GNU General Public License. In this article, OpenFOAM is evaluated with regard to its suitability for the simulation of nonlinear heat conduction with and without heat source. In addition modified solver for modeling of electric heating of solid materials is presented. To validate OpenFOAM test cases were set up and the results were compared with commercial software that has similar computational capabilities and with theoretical data. Test cases: steady-state nonlinear heat conduction in multilayer plane wall; steady-state heat conduction with heat source in two cylinders in contact; Joule heating of 3 square rods with different thermal and electric properties. The results obtained from OpenFOAM were in good agreement (near 1 %) with both numerical and analytical solutions.uk
