Experimental and Computational Studies of Complex Viscoelastic Flows

将对粘弹性流体的复杂流动进行研究。这种方法是通过实验和数值模拟技术的补充使用来实现的。实验部分基于流变学特性，并结合了激光-多普勒-风速仪和流体双折射测量。数值模拟是通过使用流体的微分和积分本构描述的有限元建模来实现的。聚合物材料加工涉及复杂流体的流动特性，为了可靠和现实的工艺设计，需要极大地改进建模和预测能力。

Research will be conducted on the complex flow of viscoelastic fluids. The approach is through complementary use of experimental and numerical simulation techniques. The experimental part is based on rheological characterization, and also a combination of Laser-Doppler-Anemometer and fluid birefringence measurements. Numerical simulations are via finite element modeling using both differential and integral constitutive descriptions of the fluid. Polymeric material processing involves flow characteristics of complex fluids, and greatly improved modeling and predictive capabilities are required for reliable and realistic process design.
