Prediction of critical heat flux for water in uniformly heated vertical porous coated tubes at low pressure
This paper includes the prediction of critical heat flux (CHF) for uniformly heated vertical porous coated tubes at pressures between 0,1 to 0,7 MPa. In this study, we use a total of 742 data points of CHF for water in uniformly heated vertical porous coated tubes obtained from literature. Accuracy of correlations was estimated by calculating both the average and RMS error with available experimental data, and a new correlation is presented. The new correlation predicts the CHF data with average error 0.07% and RMS error 7.91 %
