Abstract

Flow control is used to determine the efficiency of fluid in a pipe. In this study, a fin bundle was placed downstream of the elbow to reduce the fluctuation of flow. The purpose of this research is to determine the effect of flow control in the downstream elbow with apply fin bundle. The method is numerical simulation using software analysis of a plain pipe model, a four-blade fin bundle pipe model, six blade fin bundle pipe model, with discharge variations of 0.001 m3/s, 0.002 m3/s, 0.003 m3/s, 0.004 m3/s, 0.005 m3/s, and 0.006 m3/s. By simulation tests, the use of fin bundles was only effective in tests with a discharge of 0.001 m3/s and a discharge of 0.002 m3/s and became ineffective at discharges of 0.003 m3/s, 0.004 m3/s, 0.005 m3/s, and 0.006 m3/s; it caused losses due to backflow. The highest-pressure contour viewed is the 6-blade variation, with a value of 36 kPa. The highest velocity in the contour view is the 4-blade variation, with a value of 12.25 m/s. The lowest pressure drop in the contour view is the 6-blade fin bundle, with a value of 19 kPa; the lowest score of minor head loss in the contour view is the 6-blade fin bundle, with a value of 0.63. The research needs to improve the effect of the fin bundle, especially to modification form fin like variation of the blade, thickness, and length.
