FSI-calculation of a pool cooler in case of earthquake excitation for NPP Beznau
Determination of the loads on a pool cooler induced by earthquake acceleration and pressure waves in case of earthquake.
Drawing up a 3D model of the pool cooler and the surrounding water.
Excitation of the pool walls and the supports of the cooler with a predetermined acceleration-time-distribution.
Determination of unsteady
- Pressure distributions on the cooler
- Displacement, velocity and acceleration distributions of all nodes of the cooler
- Support forces and moments
Consideration of two-way interaction (FSI) between the cooler and the surrounding water.
