Measured performance of direct-contact jet condensers

Measured heat transfer rates and condensation efficiencies of water jets condensing steam at pressures in the range of 0.9 to 4.0 kPa (6 to 29 C, saturation temperatures) are reported. Experimental variables include jet Reynolds number, water inlet temperature, steam-to-water ratio, and the concentration of noncondensible gases. Measured Stanton number appears to be a strong function of the concentration of the noncondensibles and a weak function of other variables. At minimal level of noncondensibles, the Stanton number takes on a value of 0.0017. A description of the apparatus and initial set of results are presented.
