Correlation between heat transfer and pressure drop in channels with periodically grooved parts

摘要

Correlation between heat transfer and pressure drop in channels with periodically grooved parts along the streamwise direction is investigated for various channel configurations by assuming two-dimensional and periodically fully developed flow and temperature fields. Streamwise periodic variations of the cross-section induce the bifurcation from steady-state flow to oscillatory one. Heat transfer is enhanced significantly after the bifurcation with the increase of presure drop.
