Abstract

A perturbation analysis is carried out to include the second order solution for fluid flow and heat transfer for a wide range of excitation parameters and Prandtl numbers. The results show an increase in the time averaged Nusselt number in curved pipes with pulsatile flow over that achieved in straight pipes with pulsatile flow. The increases are most evident at high Prandtl numbers, high excitation relative amplitudes, and low excitation frequencies.
