The REinforced EXhaust System (REEXS) is a local ventilation principle for industrial ventilation with improved efficiency for capturing contaminants released by working processes .This paper discusses the validation of a 3D CFD model for the determination of the capture efficiency of standard local exhaust ventilation systems.That study has shown good results in 3 ways :- Properly designed REEXS hoods , compared to conventional exhaust devices have a significant increase capture efficiency.- CFD is an excellent tool to predict different local ventilation strategies in a quantitative way.- Thanks to modern vizualisation techniques, the results of complex flow simulations are easy to understand by everybody.
