ABSTRAKT

The effect of cross-cut on the heat transfer performance and the pressure drop in a laminar wavy fin was assessed by CFD method. The concept of cross-cut is cutting fin in a direction perpendicular to the flow direction. A five-waved wavy fin with 20 degree corrugation angle was used as the two-dimensional geometry of simulation. The Cross-cut was applied at the region of right after 3rd wave peak with 0.2Dh length. As a result, the heat transfer was increased maximum 20.3% more than that of no cut wavy fin. The pressure drop was also increased maximum 6.8%. The heat transfer performance was enhanced because cutting makes flow at the middle can attach to the fin wall.
