New Approach Flow and Spill Plume Model for Wide Openings
A typical atrium smoke management setup was divided into characteristic flow regions; axisymmetric plume, ceiling jet/approach flow, rotation region and spill plume. A grid convergence study was conducted on each of the flow regions in order to determine the non-dimensional grid resolution required to obtain a grid independent solution. Rules of thumb for grid resolutions are proposed.
