    摘要: A mixed flow fan assembly uses induced reverse ambient air flow through the in-line motor enclosure for motor cooling, motor segregation from primary exhaust contamination, and augmentation of volumetric flow rate. Induced ambient airflow through openings in and/or around the base of the fan housing balances low pressure around the fan wheel and the inlet cone to inhibit primary exhaust recirculation and increase volumetric flow rate. Straightening vanes downstream of the fan wheel are used to axially reorient radial and tangential velocity components of primary effluent flow. Airfoil impeller blades have a scalloped and/or perforated single-thickness trailing edge to attenuate fan noise.

    摘要: A modified version of an induction nozzle having a central “see-through” passive zone protects the induction ports from crosswind disruption. Modified features include: (i) a full-length wind band extending below the induction port inlets; (ii) multiple full-length mounting brackets, which impede circumferential crosswind flow around the nozzle; (iii) a transverse induction port separation plate, orthogonal to the centerlines of the induction ports; and (iv) elimination of one induction port opening.

    摘要: An aspirating induction nozzle for vertical connection to the outlet of a pressurized exhaust gas flow comprises a central nozzle surrounded by a wind band and one or more guide vanes. Ambient air is induced into a mixing zone within the central nozzle to dilute the primary effluent and increase the volumetric discharge flow rate to achieve greater plume lift. The mixing zone within the central nozzle is protected from crosswind influences, which would otherwise diminish plume lift.
