This book was released on 2016 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Droplet size, as one of the critical factors that influences spray performance and drift, must be considered when selecting spray nozzles and operational setups. Characterizing a spray nozzle for droplet size is typically completed by evaluating only a select few nozzle types, sizes, and spray pressures, which typically do not provide detailed droplet size information for the entire operational space. This research proposes a structured, experimental design that allows for the development of computational models for droplet size based on any combination of a nozzle's potential operational settings. Ten nozzles with two operational settings (orifice and pressure) and one with three (orifice, pressure, and tip) were evaluated using a response surface experimental design. All models showed high levels of fit to independently collected droplet size data. The computational models were integrated into a spreadsheet-based user interface that allows convenient droplet size predictions for a given nozzle setup. The developed models also allowed for a detailed analysis of each nozzle's entire operational space thereby providing users with a screening tool based on desired droplet size classification. The use of the proposed experimental design provides for efficient nozzle evaluations that can be used to determined droplet size and classification for any combination of operational settings.

Available in PDF, EPUB and Kindle. Book excerpt: The development and testing of drift reduction technologies (DRTs) have come to the forefront of application research in the past few years in the United States. DRTs can be spray nozzles, sprayer modifications, spray delivery assistance, spray property modifiers (adjuvants), and/or landscape modifications. A protocol for testing DRTs in high speed wind tunnels has been previously reported and was expanded to test spray nozzles. This manuscript reports on the initial implementation of the DRT program for conducting DRT evaluations of three spray nozzles under high speed conditions i.e., 45-65 m/s (100-140 mph), which are relevant to the aerial application of crop production and protection materials. The spray nozzles were evaluated in the USDA-Agriculture Research Service High Speed Wind Tunnel facility. The droplet size of each of the nozzles with different airspeeds, spray pressures, and orientation was measured with a Sympatec Helos laser diffraction instrument. The droplet size spectra for each test were input in a spray dispersion model (AGDISP), which calculates the downwind drift expected from a typical aerial application scenario. As compared to the reference nozzle, the three spray nozzles reduced spray drift by 70-84 % as compared to the reference nozzle. The nozzles generated spray droplets with volume median diameters 60-80 microns larger than the reference nozzle. One of the aerial application industry's best management practices BMPs is to not spray directly on the downwind edge of a field. The spray swath near this edge is moved upwind i.e., offset by 1/2 to 1 swath width. When this BMP was combined with the drift reductions from the spray nozzles, the amount of drift reduction was slightly increased; however application efficiencies increased to 93-96 %. These results demonstrate the possibility of combining multiple drift reduction tech.

Available in PDF, EPUB and Kindle. Book excerpt: Food security is one of the primary themes of the United Nations’ Sustainable Development Goals. In this regard, agricultural engineering is considered the backbone of agriculture, and agricultural mechanization is considered a helpful way to enhance crop yield and farmers’ profitability. Technology in Agriculture presents research in the field of agricultural engineering technologies and applications in agricultural equipment engineering, biosystem engineering, energy systems engineering, and computers in agriculture. It provides an overview of recent advancements in agricultural engineering and examines key aspects of emerging technologies and their applications. In addition, the book explores modern methodologies such as artificial intelligence and machine learning for agricultural mechanization.

Available in PDF, EPUB and Kindle. Book excerpt: An extensive critical compilation of the wide range of manufacturing processes that involve the application of spray technology, this book covers design of atomizers as well as the performance of plant and their corresponding spray systems. The needs of practising engineers from different disciplines: project managers, and works, maintenance and design engineers are catered for. Of interest to researchers in the field of liquid sprays, the book includes outlines of the contemporary and possible future research and challenges in the different fields of application and deals with: • sprays and their production; • sprays in industrial production processes; • processes involving vaporisation and cooling or cleaning of gases; • spray-surface impact processes; • fuel sprays for fixed plant; • spraying of hot surfaces for steel making and other metals; • spraying of molten metals. Guidance is given for the analysis and interpretation of experimental data obtained using different measurement techniques.
