A countercurrent flow limitation model is incorporated into the RELAP5/MOD3 system transient analysis code. The model is based on the form used by Bankoff et al., and it is implemented in a manner similar to the RELAP5 choking model. Simulations using Dukler and Smith’s air/water flooding test problem demonstrate the ability of the code to significantly improve its comparison to data when a flooding correlation suggested in Dukler and Smith’s study is used.
