In recent years, models based on the local condition hypothesis have provided significant correlations for the prediction fo Critical Heat Flux (CHF) when using only a few local variables. In this work, a sutdy was carried out to develop a generalized CHF correlation in vertical round tubes with uniform heat flux. For this analysis, a CHF database composed of over 10000 CHF data points, which were collected from 12 different sources, was used. The actual data used in the development of this correlation, after the elimination of some questionable data, consisted of 8951 data points with the following parameter ranges: 0.101 ≤ P (pressure) ≤ 20.679 MPa, 9.92 ≤ G (mass flux) ≤ 18619.39 kg/m2s, 0.00102 ≤ D (diameter) ≤ 0.04468 m, 0.03 ≤ L (length) ≤ 4.97 m, 0.11 ≤ qc (CHF) ≤ 21.42 MW/m2, and -0.87 ≤ Xe (exit qualities) ≤ 1.58. The results of this work indicate that regardless of the various flow patterns and regimes that exist in the wide flow conditions, the rpediction of CHF can be made accurately with a few major local variables: the system pressure (P), tube diameter (D), mass flux of water (G), and true mass flux of vapor (GXt). The new correlation was compared with five well-known CHF correlations published previously. The new correlation can predict CHF within the root-mean-sequare error of 13.44% when using the heat balance method with an average error of -1.34%
