Vortices are unloved by all bridge builders.
- They produce vibrations
- Hinder smaller boats
- Modify the river bed
A customer from Austria came with plans for a new 6-lane highway bridge over the Danube River.
We tackled the problem with Telemac-3D and Telemac-AD. Look at the first pictures: The first picture shows the final, calibrated model.
But before the prognoses comes the calibration:
The key to success is a good advection scheme! The key to avoid eddies behind the bridge is a fin before the bridge! Read more in our paper, linked in the section below.
