Abstract
An adiabatic two-field model was validated for flow around spacers in a 16-channel rod bundle (5x5) against experimental data. This methodology incorporates the uncertainties of the experimental methods and the bubble conditions within the flow. The large rod bundle simulations prove RANS methods are useful for these scenarios as a modest computational cost can achieve a high level of accuracy. The implications of non-fully-developed flow downstream of the spacer are thoroughly discussed.
