Abstract
This paper presents a numerical investigation of heat transfer through free (natural) convection inside the thermal and hydrodynamic laminar boundary layer of an isothermal and crimped vertical flat plate. The equations that governs the process are discretized by the Finite Volume Method through the ANSYS/FluentTM 15.0 software. Initially the paper aims to compare the results obtained in the numerical simulation for different mesh refining with the analytical model available in the literature. Afterwards, it is sought to verify how the boundary conditions and plate thickness influence at the flow, at the heat exchange and in the characteristic dimensionless parameters for this type of flow. The numerical data were compared with the analytical model available in the literature and showed good consent, regarding the variations in the boundary conditions, it was noticed that these conditions influence in the field of velocity and therefore in the transfer of heat.
