In this article, we compared the model results obtained by the naphthalene sublimation method with the results obtained by experiments with the real heat exchanger based on the model used in the naphthalene sublimation experiment. The results reveal that in the Reynolds number region studied in the present article, the experimental results obtained by naphthalene sublimation agree with the experimental data of the real heat exchanger under the working conditions within a 10% deviation. The heat/mass transfer coefficient obtained with an isothermal condition using naphthalene sublimation can be applied to the mixed thermal boundary condition. The effects of mounted and punched vortex generators on thermal-hydraulic performances are limited to the configuration studied in this article.
