Influence of a plenum box design on uniformity of the radial air jet issuing from a vortex diffuser
Uniformity of the radial air jet issuing from the ceiling vortex diffuser with side entry plenum box was investigated experimentally. Two different cases of diffuser plenum box design were used: plenum box with perforated plate and plenum box without perforated plate. Air jet velocities were measured under isothermal conditions circumferentially around diffuser. It was found that the jets in both cases were radially asymmetric. A simple method of quantifying radial asymmetry of the jet was proposed and used to compare two cases. Analysis showed that the jet issuing from the diffuser with plenum box that has perforated plate is somewhat more symmetric.
