Experimental investigation on fluid–structure interaction phenomenon caused by the flow through double-plate structure in a narrow channel

Abstract An experiment was carried out to research fluid–structure interaction (FSI) phenomenon on the parallel-plate fuel assembly. The parallel-plate fuel assembly was simplified as a double-plate structure installed in a narrow rectangular channel. In the experiment, the narrow-frequency, large-amplitude and opposite-phase vibrations and same-phase bends of two plates were observed in the different flow rate ranges. Compared with the behaviors found in the single-plate structure, some different characteristics were discovered.
