Viscosity of pure and mixed NaCl and CaCl2 aqueous solutions at 293 K to 353 K and 0.1 MPa

This project has been funded by the German Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection (BMUV, grant agreement No. 0325217), the European Union's Horizon 2020 Research and Innovation Programme (grant agreement No. 850626) and the Helmholtz Association. In the context of the German national geoscientific large-scale infrastructure project GeoLaB (https://www.geolab.kit.edu/english/index.php).

This data publication presents newly acquired viscosity data for synthetic aqueous solutions of sodium chloride (NaCl) and calcium chloride (CaCl₂), which have been prepared in a single salt and mixed form. The solutions covered a wide range of concentrations and mixing ratios representative of those encountered in geothermal settings. The data presented here span temperatures between 293 K and 353 K at ambient pressure.

The measured data were obtained at the Laboratory for Fluid physics at GFZ German Research Centre for Geosciences.

本数据出版物呈现了新获取的氯化钠（NaCl）和氯化钙（CaCl₂）合成水溶液的黏度数据，这些溶液以单盐和混合形式制备。溶液的浓度和混合比范围广泛，可代表地热环境中常见的情况。本文呈现的数据涵盖常压下293 K至353 K的温度范围。

测量数据由德国地球科学研究中心（GFZ）流体物理实验室获取。
