我们提出了大涡模拟的子通道雷诺数Re{sub h} = 4684-29184的绕丝燃料组件中的流动。该域由一个单一的针在一个六边形周期性阵列,对应于两个内部子通道。周期性边界条件也用于在一个单一的绕线周期的轴向方向。
We present large-eddy simulations of flow in a wire-wrapped fuel assembly at subchannel Reynolds numbers of Re{sub h} = 4684-29184. The domain consists of a single pin in a hexagonally periodic array, corresponding to two interior subchannels. Periodic boundary conditions are also used in the axial direction over a single wire-wrap period.
