Title Velocity profiles around hoods and slots and the effects of an adjacent plane
Bibliographic information 1982, Vol.25, No.4, p.365-372. Illus. 3 ref.
Abstract Results of measurements around local exhaust ventilation hoods and slots up to an aspect ratio of 16:1, taken with the hoods freely suspended and when resting on a plane surface, are given. A nomogram, previously designed to predict centreline velocities in front of freely suspended hoods, can also be used for hoods resting on a plane surface. Flanged hoods are more effective, and much higher velocities can be produced in front of a hood resting on a plane than with a freely suspended hood.
