| 英文摘要 | One of the most common systems in engineering problems is the multi-column system in the form of an equilateral-triangular arrangement. This study used three-dimensional numerical simulations to investigate the flow around three cylinders in this arrangement at the super-critical Reynolds number Re = 3 x 10(6), concentrating on the influence on the spacing ratio (L/D) among cylinders. The instantaneous vortex structures, Strouhal numbers, fluid force coefficients, and pressure distributions are analyzed thoroughly. The present study demonstrated that fluid dynamics is sensitive to L/D, by which five different flow patterns are classified, namely single bluff body flow (L/D <= 1.1), deflected gap flow (1.2 <= L/D <= 1.4), anti-phase flow (1.5 <= L/D <= 2.3), in-phase flow (2.5 <= L/D <= 3.5), and co-shedding flow (L/D >= 3.5). Critical bounds are identified by significant transitions in the flow structure, discontinuous drop and jump of St, and force coefficients. |
