Turbulent unsteady flow and heat transfer in channels with periodically mounted square bars

Dynamic behavior of flow around rows of square cylinders kept in staggered arrangement

“…Gu and Sun (1999) reported the results of a wind-tunnel investigation on the interference between two identical parallel circular cylinders arranged in staggered configurations at high subcritical Reynolds number. Valencia and Cid (2002) numerically investigated the unsteady turbulent flow and heat transfer in a channel with streamwise periodically mounted square bars arranged side-by-side to the approaching flow for a Reynolds number of 2 Â 10 4 . Balachandar and Parker (2002) addressed Hopf bifurcation and the associated Karman vortex shedding phenomena for a periodic array of rectangular cylinders in both inline and staggered arrangements.…”

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

“…Although the square geometry of the obstacle is relatively easy to simulate on a cartesian grid and the low-Re requires only modest computing resources, very few numerical studies have been carried out to date [23,24]. In the present numerical study (conducted using the lattice Boltzmann method, LBM) of the flow behind two square cylinders, a comprehensive analysis of both the synchronized and flip-flop regimes is carried out.…”

Numerical Study of Periodically Fully-Developed Flow and Heat Transfer in Channels With Periodic Semi-Circular Tube

“…Available at www.ThermalFluidsCentral.org model, save computing resources, and present the flow field and temperature field around the tube banks more clearly. Valencia et al (2002) studied the factors affecting unsteady heat transfer characteristics in periodically fully developed channels with rectangular obstacles. Stalio et al (2011) studied the convective heat transfer in a channel with rectangular cavities and it was found that the heat transfer strongly depended on the flow separation.…”
