    Abstract

    alkali-chloride solutions of the binary systems, LiCl–H2O, NaCl–H2O, and KCl–
    H2O, from 273K to 623 K, and from 1 bar to 1,000 bar and up to high ionic strength.
    The valid ionic strengths for the LiCl–H2O, NaCl–H2O, and KCl–H2O systems are
    0 to 16.7mol · kg−1, 0 to 6mol · kg−1, and 0 to 4.5 mol · kg−1, respectively. Comparison
    of the model with about 4,150 experimental data points concludes that the
    average absolute viscosity deviation from experimental data in the above range is
    within or about 1 % for the LiCl–H2O, NaCl–H2O, and KCl–H2O mixtures, indicating
    the model is of experimental accuracy. With a simple mixing rule, this model can
    be extrapolated to predict the viscosity of ternary aqueous alkali-chloride solutions,
    making it useful in reservoir fluid flow simulation. A computer code is developed for
    this model and can be obtained from the author: (maoshide@cugb.edu.cn).An accurate viscosity (dynamic viscosity) model is developed for aqueous
