摘要(Abstract)：
利用ANSYS-Workbench大型有限元软件建立了二维模型,在Fluent的工作环境下,探究了不同间距下不同柱体粗糙度对并联双圆柱的升力系数、阻力系数的影响。采用SST k-ω湍流模型,雷诺数控制在1×10~6,并联双圆柱的间距比T/D分别为1.5、2.0、2.5、3.0,进行了柱体表面粗糙度Rh在0、0.1%D、0.3%D、0.5%D、0.8%D和1%D时的数值模拟。结果表明:间距比为1.5时,阻力系数达到最大,升力系数上下波动峰最高;在同一间距比下,随着粗糙度的增加,阻力系数先增大后减小,粗糙度在0.5%D时阻力系数达到最大;并联双圆柱由光滑面发展到粗糙面,阻力系数会发生突变,证明了光滑柱面下的阻力系数最小和升力系数的波动峰值最小。基于以上研究,可以将结论应用于以后圆柱绕流的理论研究和桥梁墩柱的工程建设中。
