This document studies heat transfer characteristics of laminar air flow in parallel-plate channels with dimples. It introduces forced convection and how dimpled channels can enhance heat transfer over ribbed channels by increasing flow disruption and lateral mixing while maintaining lower pressure drop. The document presents the channel geometries studied, boundary conditions, analyses of streamlines, velocity and heat flux distributions, and variations of Nusselt number with Reynolds number, number of cavities, and dimple depth. It concludes that a relative dimple depth of 0.2 optimizes wall heat flux and mean Nusselt number.
