The single-phase confined and submerged jet impingement heat transfer studies in Part I are extended to two-phase flows with Freon R-113. Correlations are developed showing the influence on heat transfer of jet Reynolds number, flow quality, plate spacings and, for multiple jets, pitch-to-jet diameter ratio. Nusselt numbers are referenced back to single-jet, single-phase conditions. It is shown that the heat transfer rate can be improved significantly over that possible with a single-phase liquid operating with the same geometry although, depending on configuration, the pressure drop encountered with two-phase cooling may not be acceptable.
