Abstract
The problem of condensation of vapors flowing with high velocity aroun d a horizontal tube is solved for the case of isothermal condition of the wall of a condenser tube. The interfacial shear at the vapor conde nsate film is assessed with the help of Colburn analogy. Extension of these results in the estimation of average condensation heat transfer coefficients is found to be successful. The present theoretical result s are further compared with the recent experimental data and the agree ment between the two is found to be very satisfactory. (C) 1997 Elsevi er Science Ltd.
