摘　　要：采用通用的CFD NHT软件PHOENICS 3 2和BFC计算网格生成技术 ,对ADS靶件束窗下方有无导流板两种靶件结构冷态下的流场进行数值模拟。描述了靶区流场数值模拟的方法 。Numerical simulations of flow field were performed by using the PHOENICS 3.2 code for the proposed spallation target of accelerator-driven subcritical reactor system (ADS).The fluid motion in the target is axi-symmetric and is treated as a 2-D steady-state problem.A body-fitted coordinate system (BFC) is then chosen and a two-dimensional mesh of the flow channel is generated. Results are presented for the ADS target under both upward and downward flow,and for the target with diffuser plate installed below the window under downward flow.
