Offset strip fins are used to increase the heat transfer coefficient as well as heat transfer area in compact heat exchangers. The formation and disruption of boundary layer takes place periodically in offset strip fins yielding high heat transfer coefficient, especially near the leading edge of each periodic portion. To characterize these effects, a computational study of flow and heat transfer in offset strip channels is performed. The Reynolds number in the laminar range (10 < Re < 2000) is considered and a range of Prandtl number is considered. A parametric study is also performed.
