Abstract:

Theoretical simulation of the rheological properties of liquid media containing solid anisometric particles is performed. Procedures for the calculation of the degree of ordering in the nematic systems under equilibrium conditions and their rheological characteristics are proposed. Earlier developed notions of the calculation procedures for the properties of systems considered are analyzed and corrections to the theory are substantiated. Based on developed model notions, equilibrium and transport equations are derived and a program for their numerical solution is proposed. Model calculations of the lines of phase transition and the ordering of systems containing isotropic and nematic phases, as well as anisotropic (in orienting field) and effective dynamic viscosities under the conditions of free flow of such systems, are carried out at various concentrations and geometry of anisometric particles. A comparison of calculated and experimental data for the solutions of polymer-salt compositions with induced chain rigidity demonstrates the adequacy of the model proposed.
