Abstract

Abstract

Based on the experimental results of single-phase reverse flow in an inverted U-tube steam generator (UTSG), the primary and secondary sides of the experimental section are modeled proportionally by the method of 3D computational fluid dynamics (CFD). The Realizable k-ε model is selected for turbulence calculation, and the grid independence is verified. By comparing the numerical simulation results with the experimental data, it is found that the calculated values are in good agreement with the experimental values. At the same time, it is found that the critical velocity increases with the increase of the primary side inlet temperature and the decrease of the secondary side temperature; The operating pressure at the primary side has little effect on the critical flow rate.
