Three dimensional flow around a circular cylinder confined in a plane channel

Abstract: This paper presents two- and three-dimensional direct numerical simulations of the flow around a circular cylinder placed symmetrically in a plane channel. Results are presented in the Reynolds number range (based on the cylinder diameter and centerline velocity) of 10 to 390 for a blockage ratio (ratio of the cylinder diameter to the channel height) of 0.2. The aim of this work was to investigate in detail the confinement effect due to the channel’s stationary walls on the force coefficients and the associate… Show more

“…The channel inlet is located at a distance of L i ¼ 12:5D upstream of the circular cylinder, while the outlet is placed at L o ¼ 35:5D behind the body. These choices have been based on the previous work of Kanaris et al (2011), who repored the emergence of mode A and mode B three-dimensional wake instabilities in the transitional wake of a Newtonian fluid in the same flow configuration. A similar cylinder placement has also been used by other authors (Zisis and Mitsoulis, 2002;Mitsoulis, 2004;Tokpavi et al, 2008).…”

“…URANS equations were solved by applying finite volume scheme in these simulations. Kanaris et al [10] also investigated flow around circular cylinder in a plane channel by two and three-dimensional DNS method. These analyses were conducted at low Reynolds numbers and vortex shedding was captured in different cases.…”
