Abstract

The paper presents the rheological behavior study of the mixtures of castor oil with two types of adipic esters. The influence of adipic esters’ structure and concentration was determined, as well as that of temperature, on the rheological behavior, by setting the dependence between the shear stress t and the shear rate . The analysis of the dependence between t and demonstrates that the studied solutions present Newtonian behavior. The evolution of samples' viscosity with temperature was characterized by Arrhenius type equations, being established the values of viscous flow activation energy, Ea. It was also realized a characterization of annulus fluids flow under the effect of rotational motion, calculating the values of dimensionless criterion Taylor-Reynolds (TaRe).
