Simulation of thermal transfer using the immersed boundary method and adaptive mesh
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.
