The investigation and modelling of effect of base permeability on air entraining vortex belongs to intake in still-water environment

In this study, the experiments were realized as used critical submergence values which have been yielded depends on different radius for circle and square cross section and different intake flow rates realized by means of still water tank experiment equipment in laboratory and also by taking into account the difference base permeabilities (permeable and non-permeable base). The experiment results were compared firstly with critical spherical sink surface method. Secondly, models were created by using neural networks method and multiple linear regression method. The critical submergence values were predicted and were compared with the models.
