MATHEMATICAL MODELLING OF CaCl2 AQUEOUS SOLUTIONS THERMOPHYSICAL PROPERTIES

Abstract

Calcium chloride is an inorganic salt used in its solid state or as aqueous solutions in a multitude of research and industrial areas going from chemical industry to food, cosmetics or drugs production. This paper was directed to establish mathematical models relating its density and dynamic viscosity with factors such as temperature and concentration since it is known that these properties present a high influence on appropriate transport pipes dimensions and industrial equipment choosing and / or designing processes. The assessment and selection of the adequate models were realized by testing various software’s and equations. The obtained results revealed that calcium chloride aqueous solutions studied thermodynamic properties can accurately be expressed by quadratic (density) and respectively by linear equations (dynamic viscosity) or by more complex equations. Correlation coefficient, relative error and ANOVA values revealed no significant differences between experimental and calculated data.
