Fluid-structure interactions in pressure-suppression pools: small-scale experiments and analysis

Experiments were conducted in a laboratory scale system to investigate fluid structure interaction effects on hydrodynamically induced boundary pressure histories. A single flexible member--clamped circular plate--formed the base of a cylindrical water pool. Numerical solutions for the complete perturbed pressure histories are compared with the experiments. Ratios of the peak pressures in the flexible and rigid systems for a pressure pulse of variable duration are predicted analytically and compared with the experiments. 12 refs
