Abstract:Applying staggered meshing and two-step solving algorithm,numerical investigation on the unsteady natural circulation(including injection enhancing) chilldown process was carried out based on one-dimensional non-equilibrium two-fluid model and specific-established injector model.Circulation flow features,effectiveness of injection enhancement and chilldown were quantitatively presented and assessed.Furthermore,the effects of some parameters of system on chilldown states and process were discussed by numeric...
Keywords:circulation chilldown  natural circulation  injection  non-equilibrium two-fluid model  numerical simulation
