Numerical Simulation of Fluid-Structure Interaction with Water Hammer in a Vertical Penstock Subjected to High Water Head

Abstract:

The theoretical model of weakly compressible coupling water hammer was established and a FSI program code was developed for coupled weakly compressible water with penstock movement. It combines the weakly compressible water source CFD code and FEM shell element code. The shell element based on orthogonal curvilinear coordinates was completed in FEAP. Meanwhile, the turbulence model in OpenFoam class library was called by using object-oriented technology. This code takes into account both the weak compressibility of water and fluid turbulence characteristics. Using this code, a fluid structure interaction analysis with water hammer was completed. The numerical results agree well with the field test results.
