WIPED FILM CONDENSATION.
Abstract
The advantages of periodic mechanical removal of steam condensate from a condensing surface have been examined experimentally and theoretically, using the theory of Sparrow and Siegel. High time average condensing heat transfer coefficients, hc = 5000 Btu per (hr) (sq ft) (deg F), have been obtained at high heat loadings, Phi = 94,000 Btu per (hr) (sq ft). Prediction of this augmentation, achieved with conventional windshield wiper blades, compares favorably with the measured results. Applications of this principle will require a new concept in condenser configuration, perhaps similar to the hollow cylindrical model used in this study. A design study is being made for a specific shipboard application. (Author)
