Abstract
There is an almost everlasting debate on the possibilities of the investigation tools for their applications in a prospective fashion (while solving the engineering tasks) and – against this fact – on the use of these engineering tools while correcting the existing technology problems. A unique chance to compare these needs of research in traffic intentions (while setting the modern road communications through southern Bosnia and Herzegovina) with the natural occurrences in the atmosphere (such is a strong north wind in this geographic region) offers us the highway section Pocitelj-Zvirovici. Exactly in such cases (and before the actual construction of this highway bridge) “for the sake” of prospective engineering, the CFD mechanism (the “toolkit” for performing the computational fluid dynamics) was applied to engage this atmospheric problem. Both as steady-state explorations (while applying the k-ε turbulence treatment) and as the time-dependent CFD-based mode, we explored the wind-strokes of 10 m/s, 20 m/s, 30 m/s and 40 m/s, expected but certainly unwanted strong gaseous flows over the bridge, detecting in this way the traffic safety edge points. The results coming from the explorations performed by the CFD tool are explained and discussed.
