Numerical Simulation of Flow Interference Between Two Circular Cylinders in Tandem and Side-by-Side Arrangements

Investigation of flow around a pair of side-by-side square cylinders using the lattice Boltzmann method

“…3b). These results are in excellent qualitative agreement with the LIF images for circular cylinders at Re = 100 and s/d = 3 of Williamson [8], and the computations of Slaouti and Stansby [18], Farrant et al [19] and Meneghini et al [20]. Anti-phase locking of vortices is seen at the beginning of the simulation primarily because the flow starts from rest.…”

“…They concluded that even when the mean velocities can be reasonably well predicted, the non-linear interaction between the wakes is appreciable in terms of second and higher-order velocity moments. Several numerical studies have also been carried out for circular cylinders [18][19][20][21]. Most of these studies which present the lift and drag coefficients as a function of time, were undertaken either to verify the various numerical schemes that were used or extend experimental results.…”

Hysteretic mode exchange in the wake of two circular cylinders in tandem

“…[4][5][6] To our knowledge, the only low Reynolds number experiments of Tanida et al 7 shows a discontinuity in the drag coefficient curve for a spacing around of 3.9 diameters. These results were further confirmed by Ohmi and Imaichi 8 and by the recent numerical simulations of Meneghini et al 9 and Sharman et al 10 To our knowledge, the most complete description of the tandem cylinder wake at low Reynolds numbers was recently given by Mizushima and Suehiro. 11 Using both linear stability analysis and direct numerical simulation, they investigated the instability of the two-dimensional wake of two tandem cylinders, which were arranged as shown in Fig.…”

Numerical Study of Flow Past Two Transversely Oscillating Triangular Cylinders in Tandem at Low Reynolds Number

“…Numerous studies focused on the classical case of flow past two stationary circular cylinders with various arrangements (Meneghini et al 2001;Kang 2003;Sharman et al 2005;Carmo et al 2008;Mussa et al 2009;Sumner 2010). Additionally, the free vibrations (Prasanth and Mittal 2009;Assi et al 2010;Huera-Huarte and Gharib 2011;Carmo et al 2013;Cui et al 2014) and forced vibrations Yang and Zheng 2010;Bao et al 2012;Bao et al 2013;Yang et al 2014) involving two circular cylinders have also been investigated extensively.…”
