Numerical Simulation for Aerodynamic Characteristics of Continuous Rigid Frame Bridges
摘要
Abstract
Bas-ed on the computational fluid dynamics ( CFD) , the method of a two-dimensional cylinder surrounded by unsteady wind flow was using to solve the beam cross-section of the Continuous rigid bridge. First, the meshing schemes are compared and optimized. The numerical simulation results are compared with wind tunnel tests results to verify the validity of the models and calculation method. Then the aerodynamic characteristics of upstream and downstream beam sections of double-width bridges under different attack angles are investigated, and compared with the aerodynamic characteristics of single bridge sections. And the coefficients of aerodynamic interference factor are obtained. The work turns out to be very important to the research of aerodynamic characteristics of upstream and downstream beam sections of double-width bridges.关键词
