Abstract
An analysis is performed of available experimental data on heat transfer in the region of very low Prandtl numbers 0.005 ⪬ Pr ⪬ 3. None of the verified models on heat transfer mechanism agrees with experimental data in the whole studied region. With regard to a small number of experimental data it is not possible to make a final decision whether the disagreement is due to inacuracies in experiments or on the side of theory.
