Heat transfer and fluid flow inside duct with using fan-shape ribs

A 2-D computational analysis is carried out to calculate heat transfer and friction factor for laminar flow through rectangular duct with using fan-shape ribs as a turbulator. The types of rib shapes are imported on the heat transfer rate and fluid flow in heat exchangers. The present study makes us...
