Abstract

A new approach to the estimation of intermediate asymptotic behaviours of fluid flows is presented. This method is based on a modified dimensional analysis in which fundamental quantities having well-distinguished orders of magnitude are accounted for with different dimensions. Thus, the effects of different physical mechanisms can be isolated inside dimensional equations. The new technique is applied to the analysis of heat and mass transfer correlations for convective flows, and to the interpretation of turbulent drag reduction by additives in wall-bounded flows.
