Prediction of critical heat flux in a rod bundle channel with spacer grids based on the Eulerian two-fluid model

Prediction of critical heat flux in a rod bundle channel with spacer grids based on the Eulerian two-fluid model

The critical heat flux (CHF) is a vital parameter influencing the safety and efficiency of reactor cores. In this study, the Eulerian two-fluid model coupled with the extended wall boiling model in STAR-CCM+ was employed to simulate the departure from nucleate boiling (DNB) phenomenon in a 5 × 5 pre...
