| An analytical study of laminar heat transfer of non-Newtonian fluid in the entrance region of a circular conduit was carried out in this thesis. An asymptotic solution is obtained for the entrance heat transfer problem, with velocity and temperature profiles developing simultaneously. The non-Newtonian fluid is assumed to be of the "power-law" model and its physical properties are assumed to be constant. The initial velocity and temperature profiles of the fluid prior to its entry are considered to be flat, and the walls of the conduit are maintained at uniform but different temperatures from that of the fluid. Numerical values of local and average Nusselt numbers as functions of Prandtl number and dimensionless, longitudinal distances have been evaluated and presented in graphical forms for both Newtonian and non-Newtonian fluids. |
