Vortex shedding from a circular cylinder near a moving wall

Flows past rotating cylinders next to a wall

“…Numerical simulations for a stationary cylinder close to a moving wall have been performed by Huang and Sung (2007). They obtained a critical vortex suppression value of G/D ¼0.28, which is close to that observed for simulations conducted with a stationary wall.…”

Flow past a rotating cylinder translating at different gap heights along a wall

“…For a circular cylinder at a gap height of G=D ¼ 0:1, Taneda (1965) observed that the vortices were separated by large streamwise distances and diffused rapidly compared with those formed when the gap height was G=D ¼ 0:6. Huang and Sung (2007) investigated the flow past a non-rotating cylinder for Re o 600 and for G=D Z0:1. They observed that the critical gap height, below which alternate vortex shedding was suppressed, decreased from G=D ¼ 0:28 to G=D ¼ 0:25 as the Reynolds number was increased.…”

Direct simulation of flows with suspended paramagnetic particles using one-stage smoothed profile method

“…Especially, the Eulerian-type methods have distinguished advantages in grid generation process and thus have been developed in diverse forms; for example, IBM (immersed boundary method), VBM (virtual boundary method), IMFE (immersed finite element method), IIM (immersed interface method), DLM (distributed Lagrangian multiplier method), SPM (smoothed profile method), and so on (LeVeque and Li, 1994;Glowinski et al, 1999;Kim et al, 2001;Peskin, 2002;Nakayama and Yamamoto, 2005;Zhang and Gay, 2007). Then, they have been successfully applied to many fluid-structure interaction problems, where the structure may be stationary or moving, rigid or flexible, and simple-shaped or complicated, while the flow may be laminar or turbulent (Kang, 2006;Deng et al, 2007;Huang and Sung, 2007;Dauptain et al, 2008;Lazarkov and Revstedt, 2008;Palau-Salvador et al, 2008;Zheng and Zhang, 2008;Lee et al, 2009;Sarkar and Sarkar, 2010).…”
