words: un-symmetric constitutive equation; anisotropic fluid; liquid crystalline polymer; stability; hydrodynamic flow; orientational motion; vibrational shear flow; rheology of polymer suspension 1 Introduction The liquid crystalline (LC) polymer is considered a typical anisotropic viscoelastic fluid. The anisotropic fluid involves not only LC polymer but also suspension liquids including......

; Abstract: Using the constitutive equation of co-rotational derivative type for anisotropic viscoelastic fluid-liquid crystalline (LC), polymer... components. A vibrational rotating flow in gap between cylinders with small amplitudes is studied for the anisotropic viscoelastic fluid-liquid crystalline polymer. The time-dependent constitutive......
Relaxation process and phase transition of lanthanide liquid crystalline complexes by photoacoustic spectroscopy ZHANG Zhongning1,YANG Yuetao1,LIU Xiaojun1,LI Junjia1,ZHANG Shuyi1 (1.Key Laboratory... temperature were obtained. Photoacoustic (PA) spectroscopy was used to study the spectral properties and phase transitions of liquid crystalline metal complexes. It was found that PA intensity......
