Abstract
A wind tunnel and method of use thereof. The wind tunnel has an airflow system which is capable of delivering air vertically down through, and optionally horizontally across, a spray chamber having transparent sidewalls, wherein spray particulates produced in the spray chamber can be analyzed through the transparent sidewalls, preferably by use of a laser. The dimensions of the spray chamber are preferably greater than that of the airflow system. The use of the wind tunnel enables a wider range and more accurate spray particle measurements, especially for an agrochemical composition, to be made in a single test environment.
Claims20
A method of analyzing spray particulates in a wind tunnel comprising an airflow system and a spray chamber comprising a transparent sidewall, wherein the airflow system is capable of delivering air vertically down through the spray chamber, said method comprising:
- spraying the spray particulates from a spray tip;
- and
- analyzing the spray particulates through the transparent sidewall,
- wherein the cross-sectional area of the spray chamber is greater than the cross-sectional area of the airflow system, and
- wherein the wind tunnel is capable of switching from a spatial particle size measurement technique to a temporal particle size measurement technique with no change in configuration.
A wind tunnel comprising an airflow system and a spray chamber, wherein the airflow system is capable of delivering air vertically down through the spray chamber, and the spray chamber comprises at least one transparent sidewall and an arm adapted to receive a spray tip which is capable of spraying particulates vertically down into the spray chamber,
- wherein the cross-sectional area of the spray chamber is greater than the cross-sectional area of the airflow system, and
- wherein the wind tunnel is capable of switching from a spatial particle size measurement technique to a temporal particle size measurement technique with no change in configuration.
The wind tunnel according to claim to 17 wherein the internal partial side walls are removable.
