气泡在粘弹性液体中溶解的研究进展
Development of Dissolution of Gas Bubble in Viscoelastic Liquid 杨锋 程文萍 刘彦昌 摘 要:在发泡塑料的制造过程中,均相气体-聚合物体系的形成直接影响了制品的物理机械性能,因此了解气泡在粘弹性液体中的溶解机理成为必然.本文讲述了气泡在流体中塌陷行为的研究进展.对Rayleigh对低粘度牛顿流体,Foqe r和Goddand在无线量线性Maxwell模型的粘弹性体,Tanasawa和Tang用oldrovd三常数粘弹模型等科学家的研究行为做了概述,总结出影响此过程的复杂的影响因素,并指出进一步的研究方向. |
