Fretting wear caused by flow-induced vibration (FIV) is a leading cause of fuel failure in light water nuclear reactors. This study describes a numerical methodology, validated with dedicated experiments, for predicting flow-induced vibrations in cantilever rods exposed to axial water flow, a paradig...
In above case of Unsteady state simulation, the strouhal number is 0.168 which is correct and near to the experimentation result provided by Eric Williams et.al it his paper ‘Simulation of cross flow Induced vibration” Conclusion: - After running both the simulation respectively for steady state...
Thus, the problem simplifies to that of flow induced by changes in pressure gradient and any relative motion of bounding surfaces, forming a wedge effect (Gohar and Rahnejat, 2008; also see Chapter 5)). Therefore, the complex flow dynamics is reduced to a manageable problem in hydrodynamics,...
