“…Perrotin and Clodic [13] used CFD to calculate flow field and heat transfer in a heat exchanger, Liu et al [14] used CFD when analysing wall condensation in a chamber. Flow and vibrations in a tube bank have been investigated with CFD by Watterson et al [15], Mohr and Gelbe [16], Schröder and Gelbe [17] and Longatte et al [18]. The list of CFD work can be made long, but no work using CFD for investigating condensation in tube banks could be found in the recently published literature.…”

“…Thus, the domain is not representing a whole tube bundle but a confined case. Reynolds number is fixed to R e = 2000, complete calculation is also leaded with Code Saturne which has been validated in various FSI studies in tube bundle systems [5,15,22]. Large displacements in the y-direction (see Fig.4 Figure 5 represents the comparison between the global velocity flow field from the complete calculation and the interpolated velocity flow field.…”

Abstract. Fluid-Structure Interactions are present in a large number of systems of nuclear power plants and nuclear on-board stoke-holds. Particularly in steam generators, where tube bundles are submitted to cross-flow which can lead to structure vibrations. We know that numerical studies of such a complex mechanism is very costly, that is why we propose the use of reduced-order methods in order to reduce calculation times and to make easier parametric studies for such problems. We use the multiphase-POD approach, which is an adaptation of the classical POD approach to the case of a moving structure in a flow, considering the whole system (fluid and structure) as a multiphase domain. We are interested in the case of large displacements of a structure moving in a fluid, in order to observe the ability of the multiphase-POD technique to give a satisfying solution reconstruction. We obtain very interesting results for the case of a single circular cylinder in cross-flow (lock-in phenomenon). Then we present the application of the method to a case of confined cylinders in large displacements too. Here again, results are encouraging. An on-going work consist in going further testing parametric studies with POD-Galerkin approach and with POD basis interpolation. A future work will consist in applications to fluid-structure interactions.

“…Longatte et al, 6 and others have performed extensive research on the flow-induced vibration of steam generators by means of both simulation and experimentation; Bakosi et al, 7 Mohany and Hassan, 8 and Bhattacharya and Yu 9 mainly examined the fuel rod under flow-induced vibration. Recently, Rahman et al 10 analyzed hydraulic force (lift-off and hold-down force) of three types of high-performance annular fuels and found that the hydraulic force acting on the fuels was affected greatly by the configuration of fuels.…”

In this study, we conducted a simulation investigation of a hypothetical core barrel assembly drop accident based on the dynamic mesh model. The investigation included three separate circumstances: high-temperature dynamic water, hightemperature still water, and low-temperature still water. Results showed that dynamic parameters (e.g. velocity and resultant force) of the drop assembly in high-temperature dynamic water are smaller than those in still water due to the buffer effect of the flowing water. The velocity and hydraulic force in the dynamic water situation increased quickly at first and then remained stable throughout the remainder of the experiment; due to turbulence effect, the hydraulic force fluctuated slightly, first increased, then decreased, and then reached as stable a level in still water as that in dynamic water. The velocity of the drop assembly showed parabolic growth.
