Numerical investigation and recommendations for push-pull ventilation systems

Numerical simulations of push-pull ventilation systems are presented in this paper. That device is commonly used for the capture of pollutants form large tanks used in industrial chemical processes. For that study a finite volume model coupled with a standard turbulent model has been employed to describe the flow structures and their characteristics (dispersion, transition, encapsulation and strong suction). Other geometric parameters that influence the flow characteristics have been analyzed such as flange size, pull-channel size, offset distance.
