2001 Technology for a Sustainable Environment: A fundamental experimental investigation of the spraying of low viscosity elastic liquids (TSE01-E)

abstractcts - 0124536 g。这个项目将研究少量弹性对流过喷嘴的流体性能的影响。这项工作的动机是农业喷洒行业希望产生相对单一的液滴大小分布，可以有效地针对特定的作物区域，并避免在邻近的土地上分散。这一普遍问题因以下几个问题而变得复杂，包括：(1)喷嘴设计和应用方法的变化，(2)流体性质的变化，以及(3)不同应用场合对不同尺寸液滴的要求。在这个项目中描述的研究将提供基本的实验结果，将解决上述所有问题。众所周知，在喷涂应用中，加入聚合物可以提高液滴性能。这项工作将集中在具有良好特征的弹性液体上，这些液体将被用于精心设计的喷嘴中，以确定材料特性和几何形状对喷雾特性的影响。

AbstractCTS-0124536G. Harrison, Clemson UniversityThis project will investigate the effect of small amounts of elasticity on the performance of fluids flowing through spray nozzles. The work is motivated by a desire in the agricultural spraying industry to produce relatively monodisperse drop size distributions that can be effectively targeted to specific crop regions and can avoid dispersion over adjacent land. This general problem is complicated by several issues, including (1) variations in nozzle design and application method, (2) variations in fluid properties, and (3) requirements for different sized drops for different applications. The research described in this project will provide fundamental experimental results that will address all of the issues outlined above. It is well known that adding polymer can enhance the drop properties in spraying applications. This work will focus on well-characterized elastic liquids that will be employed in carefully designed nozzles to determine the impact of material properties and geometry on spray properties.
