Abstract

Heat and flow characteristics of V-shaped protrusion/concavity combination with 45° miniature V-rib has been investigated numerically at flow Reynolds number of 50,000. With suitable baseline studies, a total of six different configurations viz. (a) V-rib only, (b) ‘V-rib and V-protrusion’, (c) ‘V-rib and V-concavity’, (d) V-protrusion only, (e) V-concavity only, (f) Sparse V-rib, were studied in a square channel with the above features installed on single wall. With air as the working fluid, the heat transfer mechanism and pressure drop characteristics were compared for all the configurations. The compound configuration of ‘V-rib and V-protrusion’ exhibited the highest thermal hydraulic performance (THP) of 2.15.
