      <subfield code="a">The concept of capture efficiency as a design parameter for Local Exhaust Ventilation systems is presented. A theoretical model, based on computer-generated streamline maps, is developed for predicting the capture efficiency of a flanged circular hood operating with a crossdraught blowing perpendicular to the centreline. Potential applications of capture efficiency to the design and improvement of Local Exhaust Ventilation systems are discussed</subfield>
