CFD modelling of boiling in rod bundles

Krepper, E.; Rzehak, R.

Abstract

The presentation shows the application of the CFD wall boiling model on the computation of a rod bundle. The data of the OECD/NEA Benchmark Based on NUPEC PWR Subchannel and Bundle Test (PSBT) were used. Besides the parameters of the wall boiling model the simulation of turbulence in the narrow channels is essential.

Keywords: CFD; two phase flow; wall boiling; rod bundle; OECD benchmark PSBT
