✦ Synopsis

The main objective of this work is the consideration of local heat transfer coefficients for non-Newtonian power-law pseudoplastic liquid in laminar flow in circular conduits. The wall boundary conditions chosen are cases involving uniformly constant heat flux and step change in heat flux. Analytical solutions are developed for the wall temperature profile and compared with experimental data. Additionally, the experimental data have been correlated for comparison with existing relationships, hitherto not verified adequately. The limits of experimental data are: 0.34sn < I.0 lb, set" 0.02 x lo-3Q K <715x 10-37 8OOs(q/A), G 130OOBtu/hrft* tTo whom correspondence should be addressed.
