Abstract
In this paper, the turbulent natural convection for parallel plates was calculated by Large Eddy Simulation (LES) in order to clarify the thermo fluidic characteristics of turbulent natural convection between the heated vertical parallel plates. LES with the dynamic Smagorinsky model was selected for the turbulent model. Velocity and temperature fields were analyzed and the local heat transfer rate of each modified Rayleigh number was compared to that of the single vertical case. In addition, the averaged heat transfer rate was estimated with each modified Rayleigh number and compared to the laminar natural convection of parallel plates.
