Eyring模型的修正及液体混合物粘度的研究

MODIFICATION OF EYRING'S MODEL AND STUDY ON VISCOSITY OF LIQUID MIXTURES

在化工传质和流体力学中,粘度是一个不可缺少的物性.为此,已建立了许多计算液体混合物粘度的经验和半经验方程,其中不少建立在 Eing粘度理论的基础上,但这些方程都含有

The molecular model of viscous flow of liquid proposed by Eyring is modified from tworespects, namely, the activated energy of viscous flow and the frequency with which activated molecule falls into the hole. A viscosity equation with a single adjustable parameter is obtained, which can be satisfactorily used to correlate and predict the viscosity of various liquid mixtures except aqueous systems. The calculated results show that the agreement with experimental values prevails over Grunberg - Nissan and Wei - Rowley equations etc.
