Abstract

Heat/mass transfer characteristics of a circular jet impingement in cubical cavity with flat or curved bottom surface are investigated experimentally using naphthalene sublimation technique. The effects of the distance between jet exit and bottom surface (H) and jet Reynolds number are parametrically studied. The jet Reynolds number varied from 7 × 103 to 1.1 × 105, and the ratio of H/D (D-jet delivery nozzle diameter) varied from 0.5 to 4.0. The surface averaged Sherwood numbers for the bottom and lateral walls are correlated with jet exit Reynolds number by a power law equation. In the parameter range tested, the averaged Sherwood number of the bottom surface is always lower than that of the lateral walls.
