| Abstract: | In this paper, the Large Eddy Simulation (LES) was used to study the free surface turbulent channel flow wit h passive heat transfer. The three dimensional filtered incompressible Navier Stokes equations and energy equation were numerically solved with dynamic Subgri d Scale (SGS) models for modeling turbulent stresses and heat flux. To compare the turbulent behavior of the free surface and two walled channel flows, the LES of two walled turbulent channel flow was performed. The statistical quantities and flow structures of the free surface turbulence with heat transfer in the vicinity of the free surface were investigated. The results are also in good agreement with theoretical analysis and available resul ts by Direct Numerical Simulation (DNS). |
