An exact solution for creeping viscoelastic flow and heat transfer in a curved rectangular duct is presented based on the order of magnitude technique. Here, the Criminale-Eriksen-Filbey model is used as constitutive equation. The closed form of axial velocity, flow rate, flow resistance ratio, pressure distribution, stress field, temperature and Nusselt number are presented, and the effect of aspect ratio, curvature ratio and both of the first and the second normal stress differences on the flow and heat transfer are investigated. One of the noticeable results of current research is confirming the independency of flow resistance and Nusselt number of creeping flow inside the curved duct to curvature ratio at aspect ratio 0.89077.
