Wind barriers are nowadays commonly placed on bridges to protect vehicles from adverse cross-wind effects. In addition this beneficial influence, wind may adversely affect the bridge dynamic stability. This is particularly exhibited for long-span cable-supported bridges. It therefore scope of present study analyze effects aerodynamic and aeroelastic characteristics bridge-deck sections together with respective flow around sections. The focus various arrangements barriers, i.e., (1) at...
This study focuses on modifications in bridge aerodynamic and aeroelastic behaviors due to stationary (nonmoving) vehicles for various arrangements of a deck. Dimensionless force moment coefficients, as well flutter derivatives, are analyzed experimentally wind tunnel the model with semibluff cross section. A comparison is provided placed leeward, windward, all traffic lanes, an empty bridge-deck Drag, lift static forces, coefficients determined incidence angles. Flutter derivatives obtained...
Basic aerodynamic characteristics of a generic open-wheel race car equipped with various devices are studied.The focus is on the influence underbody design and front rear wings forces experienced by car.Computational simulations carried out assuming steady viscous fluid flow using Reynolds-averaged-Navier-Stokes equations standard shear stress transport (SST) k-ω turbulence model.The lift force in configuration flat (without diffuser at trailing edge underbody) without positive (undesirable...
Computational model was developed to investigate aerodynamic forces acting on a closed-wheel race car. A particular focus the effects of ground clearance and rake angle drag lift forces. Computations were performed for steady viscous fluid flow using realizable k-ε turbulence non-equilibrium wall functions. The computational results indicate strong influence loading largest force coefficient obtained clearance. squatting car is larger by 5% compared reference case, where both front rear...
Laboratory experiments were carried out to investigate pressure drop in excess flow safety valves (EFSVs) assuming isothermal, incompressible, and one-dimensional gas flow. A particular focus was on Reynolds number effects. The analyzed quantities included at the EFSV inlet outlet cross sections, rate, temperature, as well open cross-section area of EFSV. performed for various numbers, pressures, areas results indicated some important findings. In particular, coefficient decreased increased....
Long-span cable-supported bridges, characterized with low natural frequencies and mechanical damping, are very sensitive to wind effects. Therefore, investigation of the aeroelastic behaviour bridges is particularly important when designing these complex engineering structures. The focus on evaluation dimensionless coefficients, i.e. flutter derivatives, which considered as indicators stability bridges. A comprehensive experimental study dynamic wind-induced Kao-Pin Hsi Bridge in Taiwan...
