Viscosity of aqueous calcium chloride solutions at high temperatures and high pressures

摘要: Abstract Viscosity of six (0.10, 0.33, 0.65, 0.97, 1.40, and 2.00) mol kg−1 binary aqueous CaCl2 solutions has been measured with a capillary-flow technique. Measurements were made at pressures up to 60 MPa. The range temperature was from 293 575 K. total uncertainty viscosity, pressure, temperature, composition measurements estimated be less than 1.6%, 0.05%, 15 mK, 0.014%, respectively. effect concentration on viscosity studied. values CaCl2(aq) compared data, predictions, correlations reported in the literature. pressure coefficients studied as function temperature. data have interpreted terms extended Jones–Dole equation for relative (η/η0) accurate calculate A- B-coefficients derived calculated ionic B-coefficient data. physical meaning parameters V E absolute rate theory hydrodynamic molar volume (effective rigid salt) Vk using present experimental TTG model used compare predicted high pressures.
