Penetration Buoyant flow inside cavity
Conference paper UKHTC 2011
LES in progress
Numerical procedure:
Code used: Code_Saturne V2.0.1
Model used actually: K-eps with standard wall functions.
Discretization: Second order convection scheme.
First order Euler time scheme.
Boundary conditions:
Inlet:
Neumann condition for Velocity (Zero gradient dV/dy=0)
Dirichlet condition for axial and longitudinal velocities (U=0, W=0 )
Dirichlet condition for the pressure (P=0)
Dirichlet condition for the k and eps (k=,eps=)
Outlet:
Neumann condition for all the variables.
Symmetry, Adiabatic walls.
Buoyancy: Boussinesq approximation.
