Heat transfer from cam-shaped tube bank has been studied experimentally. Tubes were mounted in an in-line arrangement with two longitudinal pitch ratios 1.5 and 2. Reynolds number based on equivalent diameter varied in range of 27,000 <= Re-D <= 42,500. Drag coefficient and heat transfer from tubes in second row were obtained. Results show that drag coefficient and heat transfer of cam shaped tubes depend on position of tubes in tube bank. Tubes that located at first and second column have the maximum and minimum value of drag coefficient, respectively. In addition, Heat transfer from subsequent tubes is greater than tube in first column. Thermal hydraulic performance of cam shape tube is about 6 times greater than circular tube with same equivalent diameter. (C) 2014 Elsevier Ltd. All rights reserved.
