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, (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.
