Numerical simulation of flow past two circular cylinders in tandem and side-by-side arrangement at low Reynolds numbers

“…The maximum pressure coefficient was observed at the frontal position (θ = 0 o ); the pressure coefficient then deceases (in general) as θ increase to 180 o . Such trends agree well with the results of Lixia et al (2013).…”

Numerical investigation of flow around circular cylinder with splitter plate

“…In this figure, C p generally decreases from its maximum value at the front stagnation point, θ = 0 o , to θ = 90 o and then slightly increase to the rear, θ = 180 o , due to the recirculation of flow behind cylinder. The results show good agreements with results of Lixia et al (2013) and Sharman (2005).…”

Response and wake patterns of two side-by-side elastically supported circular cylinders in uniform laminar cross-flow

“…It is suggested by Persillon and Braza (1998) that the maximum of the blockage ratio is B ¼ 0:045 at Re ¼ 100 to eliminate the side-wall effects. However, it was reported by Qu et al (2013) that even at a very small blockage ratio of B ¼ 0:01, the difference on the hydrodynamic forces, especially the lift, caused by the side-wall effects are still perceivable. On the consideration of keeping the total number of grids within a reasonable range, the blockage ratio of B ¼ 0:04 was applied for all simulations of the VIV of two side-by-side cylinders.…”
