There are mainly two excitation mechanisms in the vibration of the thermo-well at the main pipe of reactor coolant loop under cross flow: turbulence and vortex shedding.

反应堆冷却剂回路温度计套管在流体流动冲刷下的振动主要有两种激励机理：湍流和旋涡脱落。

This method can describe the water flow velocity and vortex function distribution on all points of the reactor, with the simulation result in good coincidence with field test data.

该方法能够描绘出反应器内各点的水流速度以及涡流函数分布，且模拟结果与试验测定结果吻合得较好。
