摘要：

Accurate predictions of the heat transfer characteristics of saline solutions is of great importance for modeling the hydrodynamics and heat transfer in evaporative heat exchangers using saline solutions as the heat transfer medium. The heat transfer characteristics of NaCl solutions in a vertical heated tube were investigated experimentally to determine the heat transfer coefficients of NaCl solutions for single-phase forced convection and subcooled flow boiling conditions. The present experimental data was used to verify the prediction accuracies of existing heat transfer correlations for saline solutions. The experimental heat transfer data for saline solutions and pure water were compared to identify the main factors characterizing the heat transfer coefficient variations. A new heat transfer correlation is presented that accurately predicts the subcooled flow boiling heat transfer coefficient of saline solutions for the design and safe operation of industrial applications. © 2021, Tsinghua University Press.
