Abstract

This paper presents an analytical model for the self-excited sloshing due to the fluid discharge over a flexible weir; as observed in the cooling circuit of the French fast breeder reactor; Super-Phenix-1. To clarify the instability mechanism, we analyzed the case in which till annular reservoir was divided into till upstream and a downstream plenum by ti flexible cylindrical weir. The kinematic and dynamic effects of the discharged fluid on downstream plenum sloshing are discussed in details. Calculations are presented for the cylindrical fluid-structure model with successively increasing fluid level difference between the upstream and downstream plenums and the instability mechanism is examined.
