| 摘 要： | 板状燃料组件在先进核反应堆中得到重要应用.流体以一定的流速轴掠板状组件时会导致板后产生旋涡脱落现象.旋涡脱落有可能引发板状燃料组件的流致振动.使用BELIEF程序,通过改变方柱间距模拟了Re=200情况下刚性矩形通道内不同节距条件下双平行方柱的旋涡脱落现象,得出了双柱间节距对双平行方柱旋涡脱落特性的影响,并进一步对双平...

| Abstract: | The plate-type fuel assemblies have being widely used in the design of the advanced nuclear reactor.Vortex shedding may occur when the fluid flows over the fuel plates in axial direction at a certain velocity,which may make the plate-type fuel assemblies vibrating.Affection of the pitch between the two rectangular cylinders to the vortex shedding characteristic in the case Re = 200 in a rigid rectangular channel is given through changing the pitch to simulate the FSI phenomenon in the axial flow by the BELI... |
