The problem of heat transfer due to the steady slow motion of a Rivlin‐Ericksen fluid in the annular space between two wavy cylinders has been considered. Taking the deformation of the boundaries to be small, the equations of continuity, momentum and energy have been solved using the perturbation technique. The solution for the velocity field is employed to study the nature of the temperature distribution under two types of thermal boundary conditions. Non‐Newtonian parameters affect the velocity field, the stresses and the temperature field. The flow pattern and the temperature distribution are somewhat similar in nature to that observed in case of the way cylindrical tube in reference [5].
