Local flow and heat transfer behavior in convex-louver fin arrays

Research output: Contribution to journalArticlepeer-review


Local and surface-averaged measurements of convection coefficients and core pressure- drop data are provided for an array of convex-louver fins. For a Reynolds number range from 200 to 5400, these data are complemented with a flow visualization study and contrasted with new measurements from a similar offset-strip geometry. The results clarify the effects of boundary layer restarting, shear-layer unsteadiness, spanwise vortices, and separation, reattachment, and recirculation on heat transfer in the convex-louver geometry.
