CTS-0206666建议开展实验研究，以了解高粘性或粘弹性液体流动中液滴的变形、破碎和合并过程。更具体地说，将考察被称为相容剂的高相对分子质量表面活性剂在这些过程中的作用。试验将在小型计算机控制的四辊轧管机中进行，这些轧钢机是由PI在上一次授权期间开发和建造的。直径10-100微米的小水滴的运动和变形将通过显微视频系统进行观察和记录。
英文摘要
Abstract CTS-0206666It is proposed to carry out experimental study to understand the processes of drop deformation, breakup, and coalescence in flows of highly viscous or viscoelastic liquids. More specifically, the role of high MW surfactant known as the compatibilizer on these processes will be examined. Experiments will be carried out in miniaturized computer controlled four-roll mills developed and constructed by the PI during the previous Grant period. Motions and deformations of small drops 10-100 microns in diameter will be observed and recorded by a microvideo system.
