Abstract

In this paper is compared a proposal model for heat transfer calculations during fluid flow in single-phase inside tubes with others existing in the literature. This comparison used 3096 available experimental data of 36 different fluids. The proposal model is valid for a range from to  and 0.65 to  for Reynolds and Prandtl number respectively, dimensionless length values  and viscosity correction in the interval . The comparison proves that the suggested model presents the better index of correlation, being found an average error of 13.8% in the 80.6% of the experimental data and a maximum error of 24.6%.
