Abstract

A simplified theoretical approach for the prediction of evaporation (no-nucleate boiling) heat transfer coefficient in a horizontal tube falling film is proposed. The correlation is derived from an analysis of the thermal boundary layer under the assumption of turbulent flow regime and taking into account the thermal developing region. A diagram to evaluate h(μ22gk3) 1 3 as a function of Re and Pr is proposed. A regression analysis of the numerical computations allows us to provide a dimensionless formula h(μ22/gk3) 1 3 = 0.046 Re0.18Pr0.47 valid in the ranges Re = 1500-5000 and Pr = 1-5.
