Abstract

The data of Kutateladze related to mean condensation heat transfer coefficients of pure vapors of steam flowing in a horizontal tube are correlated considering the phenomenon as a homogenous flow. Colburn's analogy assuming to hold good the mean friction coefficients for a homogenous flow conditions are evaluated making use of heat transfer data. By extending the model further the two-phase frictional pressure drop multipliers are established. Predictions from these correlations have reasonably agreed with the magnitudes obtained from Lockhart and Martinelli correlations which are conventionally used in the design.
