Improved forced convective heat transfer correlations in the near-critical region
Abstract
The objective of this study was to compare the existing empirical approaches for forced convective heat transfer in the near-critical region and improve their predictive capabilities. Heat transfer correlations based on accurate experimental heat transfer data were developed for carbon dioxide and water in turbulent pipe flows. The important result of this study was that turbulent forced convective heat transfer to fluids in the near-critical region could be predicted by Dittus-Boelter type heat transfer correlation while using property ratio method to account for large variation of physical properties in the near-critical region. The predicted results based on the developed correlations showed good agreement with the available experimental data. The proposed correlations also show better accuracy when compared to other correlations available in the literature.
