• W4384201185 abstract "In this study, we employ a parallel Computational Fluid Dynamics (CFD) code integrated with the VTDIRECT95 algorithm, a parallel deterministic global optimization method, to conduct global optimization for an oscillating circular cylinder. We conduct numerical simulations for the flow at a Reynolds number of 500 within the parameter range of <mml:math xmlns:mml=http://www.w3.org/1998/Math/MathML id=m1><mml:mrow><mml:mn>0.1</mml:mn><mml:msub><mml:mrow><mml:mo>≤</mml:mo><mml:mi>A</mml:mi></mml:mrow><mml:mi>x</mml:mi></mml:msub><mml:mo>≤</mml:mo><mml:mn>0.3</mml:mn></mml:mrow></mml:math> and <mml:math xmlns:mml=http://www.w3.org/1998/Math/MathML id=m2><mml:mrow><mml:mn>0.5</mml:mn><mml:msub><mml:mi>f</mml:mi><mml:mrow><mml:mi>s</mml:mi><mml:mi>t</mml:mi></mml:mrow></mml:msub><mml:msub><mml:mrow><mml:mo>≤</mml:mo><mml:mi>f</mml:mi></mml:mrow><mml:mrow><mml:mi>e</mml:mi><mml:mi>x</mml:mi></mml:mrow></mml:msub><mml:mo>≤</mml:mo><mml:mn>2.5</mml:mn><mml:msub><mml:mi>f</mml:mi><mml:mrow><mml:mi>s</mml:mi><mml:mi>t</mml:mi></mml:mrow></mml:msub></mml:mrow></mml:math> where <mml:math xmlns:mml=http://www.w3.org/1998/Math/MathML id=m3><mml:mrow><mml:msub><mml:mi>A</mml:mi><mml:mi>x</mml:mi></mml:msub></mml:mrow></mml:math> represents the inline oscillating amplitude, <mml:math xmlns:mml=http://www.w3.org/1998/Math/MathML id=m4><mml:mrow><mml:msub><mml:mi>f</mml:mi><mml:mrow><mml:mi>e</mml:mi><mml:mi>x</mml:mi></mml:mrow></mml:msub></mml:mrow></mml:math> denotes the forcing oscillation frequency, and <mml:math xmlns:mml=http://www.w3.org/1998/Math/MathML id=m5><mml:mrow><mml:msub><mml:mi>f</mml:mi><mml:mrow><mml:mi>s</mml:mi><mml:mi>t</mml:mi></mml:mrow></mml:msub></mml:mrow></mml:math> corresponds to the frequency of a stationary cylinder. To enhance computational efficiency, a combination of VTdirect and a CFD solver is utilized to efficiently identify the synchronization region, thereby reducing computational resources. The results reveal a significant reduction in the lift coefficient within the synchronized region compared to unsynchronized regimes. Furthermore, the study delves into the underlying flow physics behind synchronization and lift suppression. By synchronizing the shedding of vortices, their detrimental effects are nullified, resulting in a reduction in lift. Moreover, the research examines the influence of three-dimensional (3-D) flow by comparing 2-D and 3-D simulations at two different Reynolds numbers. It demonstrates that accounting for 3-D effects yields more accurate predictions of fluid behavior. Synchronization maps and root mean square (rms) lift coefficient plots illustrate the impact of Reynolds number and movement frequency on lift suppression. The findings indicate that achieving synchronization in 3-D flow necessitates stronger amplitudes and higher frequencies. At higher Reynolds numbers, the wake structures become unstable, leading to intricate vortical patterns. Consequently, the synchronization curve shifts towards higher amplitudes and frequencies in 3-D simulations. Understanding these phenomena is vital for reducing lift force in practical applications. This research significantly contributes to knowledge regarding synchronization and lift suppression in fluid flow around vibrating cylinders." @default.
