Shear viscoelasticity of suspensions of biological cells with viscoelastic membrane II

To discuss the relaxation phenomena of biological cell suspensions, we calculate the complex intrinsic viscosity of dispersions of spherical cells with viscoelastic membrane as a function of the frequency taking account of interfacial tension at both the interfaces of the membrane. The Maxwell model and two kinds of the three-parameter models are used to describe the viscoelasticity of the cell membrane. The results are computed mainly for the Maxwell model similarly in case of the Voigt Model (Abe, K., Takano, Y. and Sakanishi, A. Biorheology 21 405-414, 1984). The computed results of the four models, the Voigt, the Maxwell and the two kinds of the three-parameter viscoelastic models, are compared with the experimental data.
