Numerical Modeling of Buoyant Flow in Penetration Cavities Using Code_Saturne V1.4.0

This study focuses on the numerical procedure used to analyze buoyant flow within cavity penetrations utilizing Code_Saturne V1.4.0. The model employs the K-epsilon standard wall functions, along with second-order convection and first-order upwind time schemes. Boundary conditions include Neumann conditions for velocity at inlets and Dirichlet conditions for axial and longitudinal velocities and pressure. Initial results are promising, with future work aimed at publishing findings and preparing an abstract for the UK National Heat Transfer Conference (UKHTC 2011).
