Heat transfer and pressure loss measurements and flow visualization were carried out for viscoelastic fluid flow in a serpentine channel in order to evaluate the heat transfer enhancement performance of using such non-Newtonian fluids. Polyacrylamide water solution was used as viscoelastic fluid. The visualized flow patterns showed that unsteady flows and longitudinal vortex-like secondary flows are generated even under the condition of$ Re<$ 2. 0 in the viscoelastic fluid case. These flows produced a remarkable heat transfer enhancement effect compared to the case of Newtonian fluid. Further, a good correlation was observed between the heat transfer and pressure loss characteristics with the Weissenberg number.
