Abstract :In this study, heat transfer enhancement of laminar pulsating flow in wavy channel is investigated numerically . The wavy channel has constant wall temperature and its geometric parameters are fixed. Finite volume method based on SIMPLE technique is used to solve governing equations. Simulations performed for Reynolds numbers in the range of 200≤Re≤800. The effects of pulsation frequency is investigated for Strouhal numbers, insert ignore into journalissuearticles values(St);  of 0.05, 0.15 and 0.25. The differences between flow structures of pulsating and steady flow are discussed. Results indicate that the pulsating flow significantly enhances heat transfer.
