Simulation numérique des écoulements autour de tabliers de pont
The dynamic response of large bridges against wind effects traditionally relies on fluid load models introducing coefficients which have to be identified with wind tunnel tests. This paper presents a comparative study of pressure fields measured on experimental sectional models and numerical results issued from moving-grid computations of the Navier-Stokes equations for rectangular and trapezoidal sections. The Proper Orthogonal Decomposition (POD) is used in order to explain profile signatures and torsional motion-induced mechanisms. Based upon numerical and experimental results, the pertinence of numerical simulations for the study of bridge aerodynamics is examined.
