✦ Synopsis

The flow field of an axisymmetric, confined and submerged turbulent jet impinging normally on a flat plate was studied experimentally using laser-Doppler velocimetry. Single jets of a perfluorinated dielectric liquid (FC-77) issuing from square-edged, geometrically similar nozzles were used in the experiments with the radial outflow confined between parallel plates. The nozzle (length to diameter) aspect ratio was unity, giving rise to a still-developing velocity protile at the nozzle exit. Experiments were conducted with nozzle diameters of 3.18 and 6.35 mm, nozzle-to-target plate spacings of up to four jet diameters, and Reynolds numbers in the range of 850&23,000. The toroidal recirculation pattern in the outflow region characteristic of confined jets is mapped. Velocities and turbulence levels are presented over a fine measurement grid in the pre-impingement and wall-jet regions.

Local measurements were made to determine recovery factors and heat transfer coefficients resulting from the impingement of transformer oil jets issuing from tiny slot nozzles of 0.091, 0.146, and 0.234 mm in width. This study focused on initially laminar jets in the range of jet Reynolds number bet
