Numerical simulations on three-dimensional behavior of separation from bridge girder and guard walls with span wise changes

Abstract

We carried out numerical simulation of a separated flow that installed the wall height field of the rod in the rectangular section. The flow field that is almost equal to basic section is formed, when the protrusion of the rod was established, when three dimensionality of a separated flow of digit upper surface was noticed. By installing the wall in half interval of the span direction, it could be confirmed that the three dimensionality of a separated flow strengthened.
