An approximate theoretical expression is derived for the ratio by which heat-transfer data, obtained from simple symmetrical flow passages, must be ‘transformed’ when applied to passages with varying roughness and heat flux around the perimeter. It is shown to be in good agreement with more elaborate theoretical treatments of special cases and with experiment.
