K. Wichterle, COLBURN ANALOGY FOR HEAT-TRANSFER IN NON-NEWTONIAN LIQUIDS, International communications in heat and mass transfer, 23(2), 1996, pp. 287-292
Generalised definition of the j-factor for power-law fluids is suggest
ed. With this definition the Colburn analogy between momentum and heat
transfer is valid for non-Newtonian now past a heated flat plate.
