Abstract

A theoretical investigation of turbulent condensing vapor jets submerged in subcooled liquids was conducted. A model of the process was developed employing the locally homogeneous flow approximation of two-phase flow in conjunction with a k-ε-g model of turbulence properties. The model was evaluated using existing data for turbulent condensing water, ethylene glycol and iso-octane vapor jets with liquid to vapor density ratios in the range 324–31,200, initial jet Reynolds numbers greater than 15,000 and negligible effects of buoyancy. Good predictions of vapor penetration lengths were obtained using conventional turbulence model constants established for single phase flows.
