Investigation on Flow Induced Vibration (FIV) in pipes is relatively new. Previous publications focused on characterizing the influences of geometric and material properties of a straight pipe. The current study investigates the influence of the curvature radius ratio in a90-degreepipe elbow for ratios (Rc/D = 1.5, 2, 2.5, 3 and 3.5). Reynolds Stress Model (RSM) is coupled with a finite element structural model to simulate the fluid-structure interaction (FSI) using one-way coupling. The RSM turbulence model and FSI model are validated against published experimental and numerical results. Preliminary results presented in the figure below indicate that vibration signal increases as the curvature ratio decreases in a quadratic manner. This functional relationship can be used as a design tool, and with further application in improving non-intrusive flow measurement techniques.
