Název v původním jazyce
Simulation of Time-dependent Pressure Fields in Model of the Control Rods of Nuclear Reactor
Popis výsledku v původním jazyce
The paper deals with the modelling of unsteady flow-field in computational domain caused by movement of the simple rigid body at fluid flow. It discusses the possibilities of CFD software to model movements and describes the new methodology of CFD simulations to solve this problem. The motion of control rods in the reactor core was chosen as a case study. The developed methodology is focused on investigating the dynamic response of the control rod model to seismic load. A number of the computational models of moving control rods with various setup of boundary conditions were created and tested. The simple database of model pressure pulses was created from the results of simulations. This database is prepared for next research use. The paper briefly describes the next steps in research of mathematical modelling and computer simulation of the seismic response of chosen control rod of reactor core cluster.
