| Abstract: | The critical flow velocities of an experimental model for the parallel-plate type fuel element assembly are theoretically and numerically analyzed. This structure is treated as multi-parallel beams joined with single-beams. According to the equations of deflection curves of beams, the continuity conditions and equilibrium at the joints, an eigen-equation is obtained for solving the critical flow velocities and destabilizing deflection curves, and it is numerically solved with implicit iteration method. |
