Rotator nozzles more uniform than spray nozzles on center-pivot sprinklers

Powder Stream Characteristics in Cold Spray Nozzles

The exponential increase of industrial demand in the past two decades has led scientists to the development of alternative technologies for the fast manufacturing of engineering components, aside from standard and time consuming techniques such as casting or forging. Cold Spray (CS) is a newly developed manufacturing technique, based upon the deposition of metal powder on a substrate due to hig...

Geologic Nozzles

Sonic velocities of geologic fluids, such as volcanic magmas and geothermal fluids, can be as low as 1 m/s. Critical velocities in large rivers can be of the order of 1-10 m/s. Because velocities of fluids moving in these settings can exceed these characteristic velocities, sonic and supersonic gas flow and critical and supercritical shallow-water flow can occur. The importance of the low chara...

Scramjet Nozzles

The lecture is given in four parts, each being a step in the process of nozzle design, and within each part the methods and techniques preferred by the lecturer are presented. We begin with a reminder concerning control volumes and the separation of aerodynamic and propulsive forces and moments. Then it is demonstrated how an appropriate control volume can help define the propulsive force vecto...

Appendix S Sediment Analysis from Water Baskets and Spray Nozzles

Measuring Spray Droplet Size from Agricultural Nozzles Using Laser Diffraction

When making an application of any crop protection material such as an herbicide or pesticide, the applicator uses a variety of skills and information to make an application so that the material reaches the target site (i.e., plant). Information critical in this process is the droplet size that a particular spray nozzle, spray pressure, and spray solution combination generates, as droplet size g...
