The Numerical Modeling as Alternative to Physical Model of Wind Flow over the Complex Terrain

This article presents the results of numerical simulation of wind flow over the complex terrain model around the Maslenica bridge in Croatia. The simulation is part of the project whose goal is the proposal of the bridge deck protection from the high wind speed. The Reynolds-averaged Navier-Stokes equations and RNG k-є model of turbulence were numericaly solved using the CFD code FLUENT. It was considered the present terrain configuration without the protection and the three different terrain configurations whith the differently shaped trench rampart which should protect the bridge deck from a high speed wind. In parallel with the numerical simulation the physical modeling was also realised. The numerical and experimental results show good agreement.
