摘要

利用数值模拟手段研究了圆柱-分离盘结构的流致旋摆响应，分析了雷诺数

、分离盘长度比

对结构旋摆响应、流场特性及水动力系数的影响。结果表明：分岔现象出现在绝大多数工况下，分岔向不分岔过渡的临界雷诺数与盘长有关，分离盘越长，此临界雷诺数越大。旋摆平衡角随雷诺数的增大先增加，后基本维持不变；分离盘越短，旋摆平衡角越大。结构摆幅随雷诺数增大先保持为零，后快速增大，最后缓慢增大或基本不变；分离盘越长，结构摆幅越大，摆幅不为零的起始雷诺数也越大。结构摆动频率主要受雷诺数影响，二者呈正相关关系。结构发生分岔并在平衡位置大幅摆动时，一个旋摆周期内在盘尖端和下侧各脱落一个旋涡，而在盘上侧由于边界层再附着存在一个滞止涡，形成回流区。发生分岔但结构基本静止时，分离盘上侧、盘尖端及盘下侧存在稳定的、尺度不一的回流区。不发生分岔时，两个相同的回流区对称分布于分离盘上下两侧。分离盘具有调控尾流和增加背压的作用，因此结构的水动力系数相比于裸圆柱明显减小。

Abstract

Flow-induced rotation of a circular cylinder-splitter plate body at high Reynolds numbers has received substantial attention. This paper numerically investigates the flow-induced rotation of a circular cylinder-splitter plate body at low Reynolds numbers

= 40～160

which has seldom been studied. Reynolds number and plate length effects on the rotation response

flow fields

and hydrodynamic coefficients are examined. Results indicate that the critical

of bifurcation is proportional to the plate length. By increasing

e equilibrium oscillation angle

mean

rises first and then arrives at a plateau; correspondingly

the root-mean-squared rotation angle

rms

rises sharply from almost zero and then varies slowly with

or remains constant. Generally

mean

varies inversely with the plate length

while the opposite is true for

rms

; the onset

of the sharp rise of

rms

is larger for longer plates. The rotation frequency is proportional to

. When the cylinder-plate body experiences the bifurcation with a strong oscillation

an individual vortex is locked on the upper side of the plate

forming a recirculation region. Additionally

two other vortices are shed respectively from the tail and the lower side of the splitter plate. When the body is static

three stable recirculation regions of different sizes are found above

below

and behind the splitter plate. When the bifurcation disappears

the splitter plate is flanked by two identical recirculation regions. Hydrodynamic coefficients of the cylinder-plate body are significantly smaller than that of a cylinder

mainly due to the efficient control of the splitter plate on the wake flow and the recovery of rear base pressure.
