Abstract

The flow characteristics around an I-type cylinder with cutting angle 53° located near a plane wall was investigated numerically in a uniform flow at a Reynolds Number of 5.3 x 104, based on a circular cylinder diameter (D). The pressure distributions along the surface of the cylinder and the plane wall were simulate by varying the gap-todiameter of cylinder ratio (G/D) in the range of 0.1 ≤ G/D ≤ 0.3, using FLUENT 6.2 software. The 2D U-RANS numerical simulation with k-ω SST as viscous model was used to visualize the flow phenomena occurred around the cylinders. The results show the existence of the bubble separation in the lower side of cylinder for the gap ratio G/D of 0.1 to 0.3. It was practically confirmed by the experimental results by measuring the pressure distribution arround the cylinder and along the surface of plan wall.
