A wind tunnel device may include a waste disposal unit configured to collect fluid from a droplet extractor positioned in a wind tunnel. The waste disposal unit may include a drain line and a liquid trap integrated in the drain line. The liquid trap may be adjustable during operation of the wind tunnel to accommodate different tunnel operating conditions (e.g., wind speeds) such that liquid waste does not backflow into the wind tunnel.

Adjustable liquid trap for liquid waste drainage under differential pressure conditions

A wind tunnel device is provided herein that enables the wind tunnel to transform between two modes of operation and/or to refresh/recondition air within the tunnel. The wind tunnel device may provide selective diversion of airflow within the wind tunnel. The diversion of airflow may enable the wind tunnel device to include a multi-configurable wind tunnel that can be operated as either an open-return wind tunnel or a closed-return wind tunnel. Additionally, or alternatively, the diversion of airflow may enable the wind tunnel device to recondition air within a closed-return wind tunnel.

Flow diverting wind tunnel

A wind tunnel device defines a cyclical tunnel to receive continuous airflow. Airflow is delivered through the tunnel to a testing region that includes a first portion carrying an arm including a spray tip configured to spray particulates in the testing region at an angle, and a second portion including an enlarged cutout region configured to receive the angled sprayed particulates. As airflow carries the angled spray particulates into the second portion, the enlarged cutout region enables the spray particulates to pass through and exit the second portion of the testing region. Analysis in the second region may be conducted through transparent walls free of openings to minimize exposure of the spray particulates to the exterior of the device. A scrubber is adapted to extract spray mist from the airflow as the airflow exits the testing region and is re-circulated through the cyclical tunnel.

Low speed wind tunnel design for agricultural spray particle analysis

The application is generally directed towards an airfoil for a fluid delivery tube. The airfoil includes a securing member operably connecting the airfoil to the tube, a fin extending downward and outward from the securing member and terminating in a tip, a shield extending inward and downward from the tip of the fin, and an air guide extending from a first end of the shield.

Airfoil for facilitating fluid delivery

The application is generally directed towards a drop nozzle for an agricultural sprayer. The drop nozzle can be used to reduce spray drift as liquids are deposited by the sprayer. The drop nozzle includes a valve assembly including a shutoff valve, a tube operably connected to the valve assembly, and an airfoil connected to the tube. The shutoff valve selectively prevents fluid flow from the valve assembly to the tube and the airfoil directs airflow around one or more portions of the drop nozzle.
