A marine riser usually works in the form of multiple riser clusters. The hydrodynamic interference characteristics between adjacent risers are obviously seen, and the interference can accelerate the fatigue damage. Therefore, it is meaningful to investigate the vortex-shedding patterns and the hydrodynamic interference characteristics of twin cylinders in order to ensure safe operation of risers. This study was aimd to parametrically investigate flows around twin moving cylinders at a staggered arrangement by a ghost cell method, in which, the incompressible Navier-Stokes equations were solved on a Cartesian staggered grid by using an in-house developed time semi-implicit finite difference method. A ghost cell method was used to enforce the no-slip boundary conditions. A radial basis iso-surface function was used to track the moving boundary implicitly and identify the properties of background grid. Based on the present numerical model, flows around twin forced moving cylinders at a staggered arrangement were simulated. Vortex patterns and force coefficients were analyzed under different gaps and oscillation frequencies. Typical interference phenomena such as synchronized, deflected and merged vortex patterns were observed. The results can provide theoretical guidance for the arrangement optimization of the riser clusters.

A marine riser usually works in the form of multiple riser clusters. The hydrodynamic interference characteristics between adjacent risers are obviously seen, and the interference can accelerate the fatigue damage. Therefore, it is meaningful to investigate the vortex-shedding patterns and the hydrodynamic interference characteristics of twin cylinders in order to ensure safe operation of risers. This study was aimd to parametrically investigate flows around twin moving cylinders at a staggered arrangement by a ghost cell method, in which, the incompressible Navier-Stokes equations were solved on a Cartesian staggered grid by using an in-house developed time semi-implicit finite difference method. A ghost cell method was used to enforce the no-slip boundary conditions. A radial basis iso-surface function was used to track the moving boundary implicitly and identify the properties of background grid. Based on the present numerical model, flows around twin forced moving cylinders at a staggered arrangement were simulated. Vortex patterns and force coefficients were analyzed under different gaps and oscillation frequencies. Typical interference phenomena such as synchronized, deflected and merged vortex patterns were observed. The results can provide theoretical guidance for the arrangement optimization of the riser clusters.

随着海洋工程结构形式的多样化,海洋立管通常以管群形式连接着水上及水下相关设备。在实际海洋环境影响下,相邻管线及柱体结构之间会存在相互影响、干扰等现象,其尾涡脱落形态的多样化严重影响立管群柱的结构动力响应安全特性,使得立管结构更易发生疲劳损坏。因此,研究多柱体在流场中的尾涡干扰及演化特征具有重要的工程意义。
目前,国内外学者对串列、并列、集群等多种布置的圆柱绕流特性做了相关研究[1-3],林凌霄等[4]运用CFD方法,数值模拟了不同间距并列布置的双圆柱流动特性,得出圆柱尾流场的不同变化。乔亚森[5]采用大涡模拟方法,对串列排列的双圆柱的二维不可压缩流动做了数值计算,发现其绕流流动特征在很大程度上取决于间距的大小,且间距存在一临界值,间距比从小于临界值变化到大于临界值,将带来一些流动动力学量的突然变化,如下游圆柱阻力系数、两圆柱升力系数振幅以及St的突然增大等。孙涵等[6]采用大涡模拟的方法研究了低雷诺数下串列双圆柱绕流问题,并剖析了其涡街结构。袁猛等[7]模拟了平行两圆柱的卡门涡街现象,并对涡量数据进行了分析。Zhao等[8]使用有限元方法对低雷诺数下串联和并联排列的双圆柱绕流进行了数值模拟,分析出不同间隙比下圆柱后方的尾流特性。胡锦鹏等[9]用CFD软件研究了并列双圆柱在不同径距比下的流动,得出了圆柱表面升阻力的分布及其变化规律。Zhang等[10]采用有限体积法对二维空间下的不等直径并列双圆柱绕流进行了数值模拟,通过对升力系数的谱分析和对流场模态的分解,阐述了两柱尾流的相互作用机理。Atkins等[11]和Alam等[12]对不同间距比下的并列双圆柱绕流进行了实验和数值模拟研究,探讨了不同间距比对间隙流的影响,通过相关研究发现,间距比小于某一临界值时,间隙流平均速度随间距比增大而增大,当间距比大于临界值时,平均速度反而会随间距比的增大而减小。
针对圆柱绕流干扰现象,许多学者采用数值模拟方法研究了两圆柱交错布置的绕流现象,发现其尾涡干扰形态特征极为复杂且不确定,并取得了一定的研究进展。Aboueian等[13]研究了雷诺数Re=150时交错排列双方柱的水动力特性,观察其在不同间距下的不同流态,并分析涡脱频率变化。Tong等[14]模拟了交错排列双圆柱对准角度从0°到90°变化等一系列工况,分析不同对准角下尾流形态对圆柱表面压力分布、尾涡脱落形态和泄涡频率等水动力特性的影响。于定勇等[15]利用Fluent软件对交错排列的不等直径的双圆柱绕流的数值特性进行了研究。Zhou等[16]采用LB(Lattice Boltzmann)方法模拟了低雷诺数下两圆柱交错布置的情况,并观察了它们之间升阻力系数的变化。Huera-Huarte等[17]对并列双圆柱涡激振动进行了实验研究,研究表明,如果两圆柱的间距大于圆柱直径的3.5倍,那么圆柱间的相互干扰就非常弱。以上数值仿真以及实验研究,并未着重分析强迫运动状态下(不同运动模式)圆柱间的相互干扰模式和尾涡脱落机制。因此,研究不同频率、不同间距的双圆柱强迫运动下相互干扰的力学模型及尾涡形态机理,有助于分析海洋工程中多种布置形式下集群立管的受迫力学干扰特征,可为立管群空间布局设计提供理论分析支撑。
本文通过研究强迫运动双圆柱绕流问题,采用自主开发的虚拟网格浸入边界法求解器,数值模拟交错布置下、具有一定运动规律的双圆柱绕流问题,分析不同参数(间距、频率)下圆柱表面升、阻力系数的变化、流场分布及尾迹干扰形态。
二维非定常粘性不可压缩流体的控制方程如下:
式中,u=(uv)为速度向量,uv分别是直角网格x-、y-方向速度分量。ρ为密度,t为时间,p为压力,µ为流体的动力粘性系数。
将以上粘性Navier-Stokes不可压缩流体方程在交错笛卡尔直角背景网格上进行有限差分法求解,并通过GPU进行并行计算。采用径向基虚拟网格法描述与捕捉结构物运动边界[20],可精确表示任意复杂结构动边界及重构虚拟网格内的流体变量。对于速度和压力的解耦通过分步求解法,并在时间上进行显式处理,采用三阶TVD-RK3[18]格式。在时间上,对流项作显式处理,粘性项以Crank-Nicolson格式进行半隐式处理。在空间上,对流项采用高阶TVD MUSCL[19]格式离散,扩散项以中心差分格式离散,采用具有Jacobi预处理技术的双共轭梯度(BICGSTAB)迭代算法求解压力泊松方程。
采用径向基函数识别出背景网格的网格属相,其中MP为镜像点、FC为流体网格、SC为固体网格、EC为物面单元中心、GC为虚拟网格单元、BI为投影点。下一步是通过引入镜像点的概念来赋值虚拟网格单元处的流体变量。镜像点与虚拟网格单元值是通过浸入边界向外法线的流体域的镜像点来一一对应,物面条件通过以上方法直接确定,并采用双线性插值方法以保证数值计算的稳定性。
图1所示,在物体边界处设置投影点BI,假设d1MPBI的距离,d2GCBI的距离,对于虚拟网格单元GC,可通过沿着d2外法向经投影点BI延伸到流体域镜像点MP,满足d1=d2;镜像点的流体变量(压力或速度分量)通过双线性插值计算得到,然后通过从流体域中的镜像点的值进行映射来确定虚拟网格单元的流体变量。最后,通过标准有限差分格式在整个计算区域上求解Navier-Stokes方程时,无滑动边界条件隐含地施加在移动边界上,简化了复杂运动物体的运动处理。根据如下公式确定投影点和镜像点:
式中,ΔLd1d2距离,n=(nxnynz)是物体表面的外法向向量,(nxnynz)分别是沿着直角坐标系x-、y-和z-方向的法向向量分量,nxECnyECnzEC为物面EC点处x-、y-和z-方向的法向向量分量。采用多项式径向基函数(PRBF)构造物面等值面函数重构任意复杂结构物边界,其计算流程分为:(1)定义流体域镜像点IP;(2)插值计算镜像点流体变量;(3)计算虚拟网格值GC
虚拟网格变量φGC根据镜像点变量通过满足如下镜像条件得到:
当施加关于速度的Dirichlet边界条件时,浸入边界的法向流体变量呈现线性变化趋势,可设置ξ1=−1和ξ2=2φBI,式中φ是各点(GCMPBI)的x-、y-或z-速度分量。当施加关于压力变量的Neumann边界条件(∂p/∂nΓ=-nΓ·aBI)时,系数计算为ξ1=1和ξ2=d2·nΓ·aBI,式中aBI是浸入边界镜像点处的加速度向量,nΓ是浸入边界的法向向量,d2GCBI的距离,然后,采用径向基函数重构物体运动边界。
本文所构建的方法在浸入物体内部布置有限数量的虚拟网格以描述物理运动边界的存在[25],此虚拟网格法易于模拟高雷诺数流动问题,同时面对复杂结构物可避免切割网格法中的小网格和不规则网格分类问题,避免了传统动网格方法中描述动物体时所产生的网格变形及重构,编制程序以及算法实现过程中也容易扩展到三维动边界问题,以上相关的技术细节阐述见文献[20-22]。
基于本文方法对不同雷诺数下单圆柱绕流进行数值计算,并采用三套不同的网格进行网格收敛性分析,以验证本文自主开发的虚拟网格求解器的计算精度和可靠性。所做算例的可靠性在文献[22]中已有验证。值得注意的是,本文虚拟网格[23-24]求解器是在CUDA环境下采用Fortran 90语言编写,适合CPU/GPU异构并行。经过良好的设计和优化,获得令人满意的加速性能。CPU主机控制计算流直到结束,包括任务分配、线程调度和事务管理,GPU设备运行计算资源消耗大的任务,而时间推进前后的轻量级任务则在CPU主机上执行[26]

圆柱绕流是经典的流动问题,具有丰富的物理现象,广泛地存在于实际的工程应用中。
本文模拟了均匀流中交错排列双圆柱的横向振荡流动现象,阐述双圆柱随间距不同的平均升、阻力系数变化曲线(1号圆柱为蓝色曲线,2号圆柱为红色曲线)。雷诺数Re=185,计算区域设置为[-5D,15D]×[-10D,10D],上游圆柱圆心取为原点,其中D为圆柱直径取1 m,T为两柱间水平间距,P为两柱间垂向间距,采用无量纲化处理,取水平间距比Gx=T/D、垂向间距比Gy=P/D。计算采用560×480的均匀网格,系统和时间步长取为∆t=0.02 s。入口处为指定均匀流,U为1 m/s,上下边界均采用对称边界,出口处采用出流边界条件。对于压力边界条件,在出口指定压力为零,其余边界均采用Neumann边界条件。两振荡圆柱的运动形式描述为
式中,ω=2πfey1y2分别是上游和下游圆柱在y方向的坐标中心,P是初始状态下圆柱表面垂向间距,fe是振荡频率,振荡幅值A=0.2D,选取fe/fo=1.2和fe/fo=1.5两种频率比。其中f0为静止绕流的涡泄频率,在算例中选取f0=0.195。
式中,为对应的平均系数,为上游圆柱平均阻力系数,为下游圆柱平均阻力系数,为上游圆柱平均升力系数,为下游圆柱平均升力系数。
图4~5分别为频率比fe/fo=1.0时两圆柱的平均升、阻力系数,图6~7为频率比fe/fo=1.2时两圆柱的平均升、阻力系数,图8~9为频率比fe/fo=1.5时两圆柱的平均升、阻力系数。由图4(a)、(b)可以发现,两圆柱平均阻力系数随Gx的增加呈下降趋势,这是由于随着两柱间距增大,柱间泄涡干扰减小,从而导致阻力减小;同时,上游圆柱平均阻力系数受Gy影响不大,但下游2号圆柱平均阻力系数随着Gy减小呈明显增大趋势,这是由于随着下游圆柱更靠近上游圆柱泄涡区,其受干扰程度加剧,从而导致阻力增大。图6(b)图8(b)是两种振动频率下的下游圆柱表面平均阻力系数,从结果中可知,随着频率从1.2增加到1.5,平均阻力系数整体呈现增长趋势,这是由于频率的增加,进一步加大尾涡脱落形态的变化,从而导致尾涡能量增大;与此同时,随着Gy增大,下游2号圆柱阻力系数呈现增大趋势,引起此现象的原因是下游圆柱更加靠近上游圆柱尾涡脱落区,受尾流干扰较严重,引起阻力增加。而将图6(b)图8(b)图6(a)图8(a)对比,从两种频率对比中,上、下游圆柱的平均阻力系数曲线,在两柱间距较小时,上游圆柱阻力系数始终大于下游圆柱,这是由于两柱间距离较小,上游圆柱泄涡受到下游圆柱的抑制而致使其阻力增大;当间距增大时,此类现象得到缓解。
图5(a)图7(a)图9(a)中可知,在两种振动频率下,上游1号圆柱的平均升力系数曲线变化趋势一致;随着GyGx逐步增大,上游圆柱升力系数呈变小趋势。以上分析表明,随着间距的增大,尾流互绕减弱,从而对圆柱表面升力影响变小。下游圆柱升力系数的值(图5(b)图7(b)图9(b))有相同的变化历程:正向的由大到小再到反向的由小到大。值得注意的是,对于上游圆柱而言,其平均升力系数的值则是一直反向减小,表明两圆柱间的干扰使两圆柱有相互靠近的趋势,造成此类原因的是泄涡产生的干扰力,使得圆柱间绕流产生了相互靠近作用,且干扰作用随着两柱间距离的增大而减小。另一方面,三种振动频率下,圆柱平均升力系数在Gy=0.6时波动变化最大,Gy=1.2、Gy=1.8则相对较小,说明间距增大柱间力学干扰特征减弱,尾涡的形态变化是干扰的主要原因。
图10展示了Gx=1.0、Gy=0.6时、三种频率fe/fo=1.0、fe/fo=1.2、fe/fo=1.5下圆柱表面的升力系数和阻力系数历程曲线(蓝色为1号上游圆柱,红色为2号下游圆柱。从图中可以看出,在fe/fo=1.5时双圆柱的升力系数反相同步周期性振荡,阻力系数呈现相同趋势变化;当频率减小到fe/fo=1.2时,上游1号圆柱(蓝色)升力系数变化幅值减小,呈现扰动趋势,下游2号圆柱(红色)由于受到上游干扰作用,升力系数呈周期性波动;两圆柱阻力系数变化相似,下游圆柱受到干扰作用波峰与波谷发生轻微偏斜;而fe/fo=1.0时,两圆柱升力系数变化存在一定相位差,随着频率的降低,升力系数的振幅稍微减小,但振动周期波动变化明显,此时两圆柱之间受力干扰明显,同时,下游圆柱升力系数曲线振幅大于上游圆柱,阻力系数均呈现不规则变化,在fe/fo=1.0时,尾涡发生融合现象,导致下游圆柱后部阻力曲线呈整体上升趋势,且最大振幅随频率比的减小而增大。
根据物体运动方程可求取两圆柱相对较远和较近物理位置时的涡量等值线图,图11-13分别给出了Gx=1.0、Gy=0.6时三种频率比下两圆柱最靠近位置和最远位置的涡量等值线图。在该间距比时,三种频率下两圆柱的尾涡均发生明显的干扰现象,当fe/fo=1.0时,由于两圆柱周期性的振动,沿着圆柱表面的剪切流呈现不稳定特征,尾涡交替脱落并向尾部方向流动;值得注意的是上游1号圆柱尾涡脱落后,受到下游2号圆柱尾部旋涡作用,产生反向旋转,并在一个周期之后,被下游2号圆柱产生的尾涡吞噬,形成一个融合不稳定的卡门涡街。随着频率增加到fe/fo=1.2,两圆柱尾涡发生变形和融合,合并成一条向上偏移的涡街,偏移程度随频率的增加而加剧;同时这种周期性变化使得融合处产生一个局部泄涡区,伴随着泄涡区的演化,两圆柱平均升阻力系数呈降低趋势。当fe/fo=1.5时,两圆柱产生的涡在圆柱后方形成介于一条涡街和两条涡街之间的耦合涡街;随着频率的增加,两圆柱尾部脱落的涡迅速融合,产生更大的局部泄涡区,涡之间发生相互排挤,导致涡形态的剧烈变形,进一步发生局部分裂演化,形成非定常状态的并排双涡。
图14展示了当间距Gx=1.0、Gy=1.2时,三个频率fe/fo=1.0、fe/fo=1.2、fe/fo=1.5下的两圆柱表面阻力和升力系数时间历程曲线。在频率比fe/fo=1.5下,两圆柱升力系数呈现反相同步周期性变化,阻力系数波动剧烈,类似于不稳定脉冲形式;当振动频率降低到fe/fo=1.2时两圆柱升力系数按一定相位差周期性变化,随着频率降低升力系数振幅减小,周期延长,曲线由正值变为负值存在一定的时间滞后。造成此类现象的原因可能是由于圆柱低频率受迫振动干扰较小,且后方尾涡脱落存在一定的融合及分裂。随着频率的降低,阻力系数受扰减缓,呈现出一定的周期性;在fe/fo=1.0时下游圆柱升力系数幅值进一步减小,呈不规则现象,同时两圆柱升力系数变化周期进一步延长,存在一定相位差,值得注意的是,在fe/fo=1.0下,上游1号圆柱(蓝色)阻力系数在t=60 s后呈长周期(60 s至150 s)性趋势,而下游2号圆柱由于受到干扰作用,阻力系数呈现不规则波动,发生轻微偏斜。
图15-17展示了Gx=1.0、Gy=1.2下,频率比fe/fo=1.0、1.2、1.5时两圆柱相距最近和最远时的涡等值线图。三种频率下,两圆柱产生的涡在圆柱后方发生不同程度的干扰,且振动频率越大干扰越明显。在fe/fo=1.0时,柱间干扰较小,两圆柱交替产生反向旋转的卡门涡街,并沿着尾部方向脱落,在后方形成两列近似对称分布的涡街,尾流远端涡街相互独立,涡街保持一定的良好形态。当频率增大到fe/fo=1.2时(如图16),柱间尾涡脱落干扰加剧,产生融合趋势,并伴随着涡裂,由于受到表面剪切流影响,脱落的漩涡呈现复杂的演化。随着频率增大到fe/fo=1.5,两圆柱脱落的对涡在尾流区域发生更加剧烈的融合现象,相互干扰、变形,并有局部泄涡逃逸,形成复杂的、随机的、不确定的复杂尾涡形态。
图18展示了当Gx=1.0、Gy=1.8时,三个频率fe/fo=1.0、fe/fo=1.2、fe/fo=1.5下两圆柱表面阻力和升力系数时间曲线。在频率比fe/fo=1.0时,两圆柱阻力系数与升力系数呈同相、同步周期性振荡,升力系数在t=40 s后保持周期性稳态,两圆柱阻力系数趋势一致,存在微小偏差;当频率增加到fe/fo=1.2时,两圆柱升力系数和阻力系数呈现反相周期性变化,有相位差。上游1号圆柱阻力系数呈规则周期性变化,下游2号圆柱受到干扰作用,阻力系数曲线变化不规则;当频率增大到fe/fo=1.5时,两柱间升力系数呈反相同步周期性变化,升力系数最大幅值加剧。下游2号圆柱阻力系数整体趋势高于上游1号圆柱,并保持一致的不规则周期性变化。值得关注的是:在fe/fo=1.5频率比下,小频率振动时两圆柱升力系数呈现同相、同步周期性振荡;当振动频率大于某一临界值时,两圆柱升力系数变化转变为反相振荡,随着频率进一步增大最终转变为反相同步振荡。而对于间距Gx=1.0、Gy=0.6和Gx=1.0、Gy=1.2未明显观察到此现象。
图19-21给出了Gx=1.0、Gy=1.8下频率比fe/fo=1.0、1.2、1.5时两圆柱相距较近和较远位置的涡等值线图。此时相比于Gy=0.6和Gy=1.2的情况,在频率比fe/fo=1.0时,由于两圆柱间间距的增大,两圆柱产生的尾涡干扰较小,尾涡脱落相互独立,并在远端存在明显干扰的分散涡列;当频率比fe/fo=1.2时,尾部涡街脱落更加频繁,在尾流区独立并紧致排列,形成一定趋势的涡街阵列。受振动频率增加的影响,fe/fo=1.5时两柱脱落的漩涡交替进行,形成两列涡街,存在一定趋势的局部融合,并偏向一侧圆柱,此时两圆柱流场特征保持相对稳定。
本文基于自主开发的虚拟网格浸入边界法模拟了交错布置的双圆柱强迫运动绕流问题,得出如下结论:
通过数值研究不同振动频率下多种间距错列布置的圆柱表面泄涡压力特征,阐明了在距离较小时双圆柱干扰较强烈,尾部泄涡处有融合现象出现,此干扰受上游圆柱运动状态的影响波动剧烈;面对不同频率及间距下两圆柱受到相互靠近压力的作用趋势,其中,随着间距的增大此趋势有所缓解。同时,分析了双圆柱在特定频率下三种距离的升、阻力系数和圆柱尾流场涡量分布及变化,总结出此类情况下双圆柱相互泄涡干扰特性:随着振荡频率的增大,升、阻力系数振幅增大,双圆柱间的干扰越强烈。值得注意的是,当双圆柱间距增大时,振荡频率对两圆柱尾流区域涡流的影响作用减弱,圆柱间升阻力系数谐和性更好。在圆柱间距较小时,振荡频率对尾涡影响起主要作用;而当间距增大到一定程度后,圆柱后方的涡列水动力性能保持较好,振荡频率对尾流的影响作用将不再占主导地位。
综上分析,数值仿真结果揭示了不同振动频率下多种间距错列布置的圆柱表面泄涡机理,有助于进一步了解强迫运动特征对错列布置圆柱绕流尾部涡脱落干扰特征机制的深入探究,下一步将从尾涡的融合及泄涡分裂等复杂物理特征方面进行更为精细化的数值分析工作。
