abstract

  • 2018 by the authors of the abstracts. In this paper, we tried to attempt to solve three dimensional unsteady turbulent channel flows in open Foam software using Reynolds Average Navier-Stokes (RANS) model. We have simulated the flow through 4X2X2 channel at frictional Reynolds Number ( * Re ) of 590 with six precessions in 48 parallel processor in work station. K- model has been used with 50,000 time steps with each of the time stepping of 0.3. Critical care has also been given for maintaining courant Number in between 0.4-0.5 for stability and convergence of the numerical solution. The velocity profile, several normal stress and Reynolds stresses variations with respect to wall have been shown, turbulence energy production, dissipation, their ratios have been compared, individual behaviour of viscous stress, Reynolds stresses and their contribution to total stress have been computed. All computations have been done by high performance parrallel computation (HPC) on 64 processor super computer.
