Following Part I of this series, its scope of application is extended to deal with the heat transfer to a turbulent forced-convective flow of a heated fluid mixture in which a positive heat of reaction is absorbed due to an endothermic reaction. Both complicacies of the multivariate problem and non-linearities of the property variations due to the reaction advancement are avoided by a specific thermodynamic perspective discussed in Part I. A simple relation for the augmentation ratio of Nusselt numbers for the turbulent case is derived, as with the prior laminar case. Some applicability evaluations are also carried out preliminarily, and their results suggest that the obtained relation provides a brief prediction of trends in the effective Nusselt numbers.
