Effect of protruding normal dividers on the turbulent flow between plane boundaries

The flow field between parallel plates produced by protruding dividers was evaluated through the predictive capabilities of the TEACH program. Such flow fields are common to wire-and-plate electrostatic precipitators. The TEACH program provides a reasonably good prediction of mean flow velocities but is inadequate for reliable pressure, turbulence energy and Reynolds stress predictions. The inadequacy of the numerical scheme is due to the assumption of isotropicity in the turbulence model.
