Abstract

The objective of this study is to investigate flow characteristics of a underwater vehicle by installing pins, using CFD method with a commercial code FLUENT version 6.3.26. To verify the reliability of the computation, the drag is compared the CFD with the experimental test. The drag is increased about 15% by installing 4 pins. At the stern of the body, the turbulent flow is generated by installing pins. Also, the results showed that the drag increase in the stern of the body, not in the pins.
