摘要：This paper presents a comprehensive review of correlations of friction factor of turbulent pipe flow under supercritical pressure to provide a guide to choosing a proper correlation for a given application and proposes a high accuracy correlation of friction factor for adiabatic supercritical turbulent pipe flow. Two databases containing 1279 experimental data points of friction factor of turbulent pipe flow under supercritical pressure were compiled from 12 available sources. One has 820 data points at adiabatic conditions, and the other has 459 data points at non-isothermal conditions. Based on the two databases, six adiabatic and 13 non-isothermal correlations are evaluated, and a new model for adiabatic supercritical fluids is developed. The new model has a mean absolute deviation (MAD) of 8.2%, while the best existing one only has an MAD of 20.4%, indicating that the new model improves the prediction accuracy of friction pressure drop of adiabatic supercritical pipe flow remarkably. © 2019 Elsevier Ltd
