description: The given work focuses on the numerical modeling of turbulent free convection between isothermal surfaces with internal heat sources. The research set for the following goals: 1. Numerical modeling using the OpenFOAM package based on the Implicit Large Eddy Simulation (ILES) approach in a three-dimensional setup. 2. Verification of the problem formulation by considering calculations without gravitational acceleration. 3. Comparison of the conducted simulations with data from other researchers using different software packages. The work was conducted using the OpenFOAM software package, utilizing its built-in tools for geometry construction, grid generation, and modeling approaches. As a result of processing the obtained results, average quantities such as temperature and heat flux were analyzed. It was concluded that this package is applicable for solving problems of this nature.
