Buoyant flow inside penetration cavity
Numerical procedure:
Code used: Code_Saturne V1.4.0
Model used actually: K-eps standard wall functions.
Second order convection scheme.
First order upwind 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.
Symetrie, Adiabatic walls.
Buoyancy: Boussinesq approximation.
Initial results
Actual work and future plans:
- Preparing tow papers to publish the previous work ...
- Preparing an abstract for UKHTC 2011 UK National Heat transfer
Conference ...
- Start to implement AWF wall functions and test different cases ...
