Abstract The forced convective heat transfer of mixed molten Hitec salts in transversally corrugated
tubes with different sets of structural parameters were obtained through experimental study. The
enhanced heat transfer mechanism in transversally tubes with different sets of parameters was inves-
tigated; the deviations between the fitting correlations under corresponding structural parameters
and experimental data were within 10%. In addition, based on the consideration of transversally
corrugated structural factors, a general correlation app
