FMP效应与电流变悬浮液在流动场中俘获效应的耦合作用

The Coupling Process of the FMP Effect and the Capture Effect of Electrorheological Suspensions in a Flow Field

通过FMP理论对我们实验中的俘获效应加以研究,可得知此过程中粒子的成链结构、粒子倾向(引起堆积形式变化的趋势)以及链状网络结构强度和有限的介电响应时间等信息.给出了电流变响应过程的一般动力学控制方程以及链崩溃时临界的剪切应力值(压力梯度值),及俘获粒子过程中有关结构弛豫时间的求法.

To research the capture effect which is defined in our experiment by the theoretic analysis of FMP effect, the information about the chain structure of the particle, the tendency of the particle movement（ that＇s, the tendency of the structure transformaion） and the chain - net- structural strength as well as the finite dielectric response time could be obtained. This paper gives the general kinetics equation as weft as the critical shear stress value （or the critical press gradient value） when the chain structure breaks down, and the method to get the structure relaxation time in the ＂structure capture particle＂ process.
