USING FLUENT AS AN EXPERIMENTAL STAND FLOW THROUGH A BROKEN BARRAGE

In the paper we propose to use the FLUENT program as experimental stand. Why do we do this? It is often difficult and expensive to achieve a model. It is also difficult to calculate the phenomena in the nature scale using the FLUENT. So we calculated the physical parameters, using FLUENT on the model and we passed them, using the similitude criteria, in the nature. We illustrated the method with a spectacular example: the flow through a broken barrage. First, we established the model law, taking into account the physical magnitudes which influence the analyzed phenomena. Afterwards we calculated the scales of these physical magnitudes for normal similitude (a single geometrical scale). Using FLUENT we determined the values of the velocity and forces acting on the barrage (the unbroken part).Finally, we passed the “experimental” data in the nature by application of scale for physical magnitudes.
