THE FLOW PRODUCED IN PARTICLE-SUSPENSION BY AN INFINITE ROTATING DISK:SERIES SOLUTION

To the flow produced in particle-suspension by a rotating disk of infinite extent,the asymptotic behavior at infinity is analyzed.A corresponding series solution is presented.It isshown that this approach yields widely valid solutions of high accuracy for all the cases in whichthat suction or weak injection at the disk surface exists.For the cases that strong injection or par-ticle-free band exists,the series method fails.     

Synthesis and characterization of poly(siloxane-urethane)s

A series of polyurethane block copolymers based on hydroxy-terminated polydimethylsiloxane and poly(propylene glycol) soft segments of molecular weights 1818 and 2000, respectively, were synthesized. The hard segments consisted of 4,4′-diphenylnethane diisocyanate and 1,4-butanediol as the chain extender. Samples with different molar ratios were prepared. We tried to synthesize polydimethylsiloxane-based polyurethanes (PDMS-PU) containing a hard block as major fraction and a soft block as minor fraction for preparing toughened rigid systems. After a study of the pure polydimethylsiloxane-based polyurethane and poly(propylene glycol)-based polyurethane (PPG-PU), (mixed polyol)-based block copolymers and blends of PDMS-PU and PPG-PU were synthesized, and characterized by means of differential scanning calorimetry, tensile testing and scanning electron microscopy. In (mixed polyol)-based copolymers and lower hard-segment content blends, macro-phase separation occurred, but blends with higher hard-segment contents showed significant reduction in amounts of phase separation.

代数应力模式的分析解及其在充分发展旋转管流中的应用

本文通过求解雷诺应力在代数应力模式中与平均速度梯度之间的分析关系，研究了代数应力模式在涡旋流动特别是在充分发展旋转管流中存在的内在缺陷，这些缺陷的主要表现为：（１）在不考虑固壁对湍流影响的代数应力模式中，分析解给出Ｗ∝ｒ和ｖｗ＝０的错误结论；（２）若在代数应力模式中考虑固壁对湍流影响，在对称轴上会有ｖ＾２不等于ｗ＾２的非物理解。与诺应力输运模式相比，代数应力模式的缺陷归限结底在于该模式的基本假设不
