초록
A numerical study of thermo-flow characteristics is presented to determine correlations of pressure drop and heat transfer for offset-strip fins. As a blockage ratio increased, previous correlations underestimate f values in laminar and turbulent regimes, and overestimate j values in laminar regime. Therefore, new correlations, which are applicable to fins with blockage ratios more than 15%, are presented.
