摘要

We consider fluid-structure interaction problems in which the fluid flows are slightly compressible, inviscid and irrotational with no heat transfer, and in which the boundary motions of the fluid domains are small. These problems are efficiently solved using the subsonic potential-based fluid formulation presented in this paper. The formulation is efficient because the fluid modeling includes only one nodal point unknown, the velocity potential. A practical example from the nuclear industry, the HDR blowdown experiment, shows the efficiency and accuracy of the formulation.
