N2 - The Navier‐Stokes equation in stream function‐vorticity form and the energy equation are solved numerically for a fully developed flow of a Newtonian fluid in coiled circular sectors having zero pitch. Two heat transfer cases are studied: axially uniform heat flux with uniform peripheral temperature and axially uniform temperature with mixed conditions along the periphery. Solutions are presented for curvature ratios in the range of 5 to 30, Prandtl numbers in the range of 0.7 to 100, and Dean numbers up to 300. In all cases studied, the heat transfer performance for the curved tubes was superior to that of a straight tube geometry.
