title: Evaluation of hoods for low volume-high velocity exhaust systems.
abstract: Current practice in the design of exhaust hoods for low volume-high velocity exhaust systems is empirical and evaluation of performance is conducted at the completed installation. A procedure is described for laboratory evaluation of prototype hoods using a simulator in conjunction with a tracer aerosol.
