Subchannel analysis method has been used to predict the critical power of a BWR fuel-rod bundle, introducing empirical spacer effects models. To construct more mechanistic models for spacer effects such as promotion of deposition, the Euler-Lagrange (E-L) method has been developed. However, this method is incapable of considering break-up process of droplets impingement on the spacer surface. In this study, we simulated the droplets behavior around BWR spacer with TF-MPS method to make a sub-model for E-L method to take the interaction between droplets and spacer into account.
