The steady laminar forced convection heat transfer from nonisothermal thin needles in nonuniform incompressible flows is investigated analytically. Similarity temperature fields and heat transfer characteristics for needles with power-law thermal variations in (1) wall temperature, and (2) surface heat flux, are obtained. The influence of needle size and Prandtl number on the thermal behavior of the flow is examined for a uniform as well as an accelerating flow.
