Investigations of heat transfer and pressure drop between parallel channels with pseudoplastic and dilatant fluids

“…For power law fluids, such solutions are also available (Beek and Eggink13 and Grigull14). For situations where the velocity profile is fully developed but the temperature profile is developing (the Graetz problem), solutions have also been reported for Newtonian fluids for both boundary conditions (Shah and London3) and for power law fluids (Bird and Hassager,15 Lyche and Bird,16 Whitman and Drake,17 Mckillop,18 Joshi and Bergles19)…”
