An analysis of the laminar steady-state forced convection heat transfer from a nonisothermal thin needle in an accelerating incompressible non-Newtonian fluid is presented. Similarity temperature profile and heat transfer characteristics are obtained for needles with axial power-law variations in surface temperature and surface heat flux. Effects of the needle size, the non-Newtonian flow behavior, and the generalized Prandtl number of the thermal characteristics of the flow are examined in detail.
