Abstract

Ventilation is important for controlling gaseous contaminant levels in workplaces, but the emissions capture distance of conventional intake hoods is limited. The vortex suction device (VSD) aims to elongate the intake flow region of local ventilation systems by exploiting the shielding features of specifically organized peripheral swirling jets. Herein, numerical CFD modeling and laser Doppler anemometry were used to investigate the confinement of intake flow by the buffer-recirculating cell shield generated from peripheral outflowing swirling jets. The measured velocity profiles yielded approximately a doubling of the intake capture distance by using the VSD equipped with a diffuser with a 90° opening angle. Potential applications for local ventilation tasks are discussed.
