Analysis of flow-induced vibration of cylinder with splitter plate based on overset grid method

In actual engineering, asymmetric flow often occurs, but rigid partitions are installed in the direction of field and symmetric direction. This will result a deflection angle between dividing plate incoming flow. The research results show that when declination is low, partition has limited impact on system; about 10 degrees, system vibration characteristics have abrupt changes, amplitude decrease, vortex frequency increase; at degrees to 45 As increases, decreases; it can be seen from motion trajectory changes suddenly after small 25 degrees. That is, this interval, better control effect cylindrical system.
