RESUMO

In the present work the mathematical modeling and simulations of turbulent flows with thermal transfer are presented. Cartesian numerical mesh is used for a non Cartesian problem, thanks to the dynamic and thermal immersed boundary methodologies. Turbulence modeling was performed using the LES (Large Eddy Simulation) metolodology with the dynamic Smagorinsky subgrid-scale modeling. All the development was carried out using a computer code developed at home (MFSim - Multiphysic Simulator). In order to exemplify the functionalities of the computational tool, simulations of the natural convection were performed on a horizontal cylinder. Consistent qualitative results were obtained, revealing the dynamic structures characterizing the transition to turbulence. The corresponding statistical results compare well with the reference results published by other authors.
