An analytical model for local heat transfer coefficients for forced convective condensation inside smooth horizontal tubes Academic Article uri icon

abstract

  • An analytical model based on annular flow is proposed for predicting the local heat transfer coefficient for forced convective condensation inside smooth horizontal tubes. The Prandtl mixing length theory, Van-Dreist's hypothesis and Reynolds analogy are used for the analysis. Experiments are conducted by condensing R-22 inside an 8.001 mm (0.315 in.) i.d. copper tube for a wide range of mass flux rates and condensing temperatures. The analytical results, compared with the experimental data and four other correlations reported in the literature indicate that 80% of the predictions are within ±25% of the experimental data, with a mean deviation of 15.3%. © 1995.
