Numerical simulations based on a three-dimensional two-way bubble tracking method are carried out to predict bubble motions in a square duct with an obstacle and in a two-by-three rod bundle with a grid spacer. Comparisons between measured and predicted bubble motions demonstrate that the two-way bubble tracking method gives good predictions for trajectories of small bubbles in the upstream side of the grid spacer in the rod bundle geometry. The predicted bubble trajectories clearly show that bubbles are apt to migrate toward the rod surface in the vicinity of the bottom of the grid spacer. Analysis of forces acting on the bubbles confirms that pressure gradient force induced by the presence of the spacer is the main cause of the bubble lateral migration toward the rod surface. Motions of steam bubbles at a nominal operating condition of a pressurized water reactor (PWR) are also predicted by using the bubble tracking method, which indicates that steam bubbles also migrate toward the rod surface at the upstream side of the spacer due to the spacer-induced pressure gradient force.

“…However, in most of the studies, mass transfer and chemical reaction are ignored amongst others due to excessive memory and computational power requirements. Research of multiphase CFD thus mainly focused on the modelling of the hydrodynamics of the reactors and improving the closures required by the model to achieve a better prediction of the hydrodynamics (Delnoij et al, 1997(Delnoij et al, , 1999Deen et al, 2001;Buwa et al, 2006;Tomiyama et al, 1997;Pan and Dudukovic, 2000;Sokolichin and Eigenberger, 1994).…”
