Experimental and Computational Studies of Complex Viscoelastic Flows

研究粘弹性流体的复杂流动。该方法是通过实验和数值模拟技术的互补使用。实验部分以流变学表征为基础，结合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。聚合物材料加工涉及复杂流体的流动特性，因此需要大大提高建模和预测能力，以实现可靠和现实的工艺设计。

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.
