【Abstract】 The flow field distribution in reactor is numerically simulated by CFD analysis tools,and the flow velocity and flow rate assignment at the fuel assembly inlet are obtained. By the comparison analysis on the calculation results, the flow characteristics in the reactors of nuclear power plant are comprehensively understood,which can provide analysis basis for the design and optimization of reactor components. The results show that it is feasible to use the CFD technology to simulate and calculate the flow field in the reactor.更多还原
