20150139823 | Aspirating Induction Nozzle with Flow Transition - High plume lift is particularly critical with regard to exhaust gases from potentially contaminated sources, such as laboratories and other facilities in which chemical processes produce noxious and/or hazardous fumes. To insure that potentially contaminated exhaust reaches a minimum altitude to avoid downwash, many applicable environmental and building codes and standards specify a minimum discharge velocity from an exhaust n discharge location. Therefore, an aspirating induction nozzle is designed to ensure that the discharge velocity is always at or above the governing guidelines while simultaneously leveraging physics to consistently induce fresh air with no moving parts. To achieve this, the flow rate from the fan at the inlet of the nozzle must be accelerated. A frusto-conical transitional flow impinger provides a mechanism to effectively control the flow velocity in the region from the discharge of the fan impeller through the nozzle body. The addition of the impinger provides a mechanism to ensure that flow velocities are always constant or increasing until the discharge plane of the nozzle body, thereby offering a means to optimize the design of the nozzle for the given flow and/or operational pressure drop requirements, while sustaining a tuned venturi effect for steadfast operation in a dynamic environment. | 2015-05-21 |
