摘要
采用通用的计算流体力学(CFD)软件PHOENICS3 3和BFC计算网格生成技术,对加速器驱动次临界系统(ADS)靶件的流场进行数值模拟计算。结果表明:束窗下方导流板起引导流体沿束窗表面流动的作用,消除了束窗两侧下方较大的旋涡,对于改善束窗附近流体的流动结构、提高束窗表面及散裂靶的换热,效果显著。
Numerical simulations of flow field are performed by using the PHOENICS 3.3 code for the proposed spallation target of accelerator-driven sub-critical 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 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 different window shapes and diffuser plates under downward flow.
