  The growing interest in energy applications of molten salts is justified by
several of their properties. Their possibilities of usage as a coolant, heat
transfer fluid or heat storage substrate, require thermo-hydrodynamic refined
calculations. Many researchers are using simulation techniques, such as
Computational Fluid Dynamics (CFD) for their projects or conceptual designs.
The aim of this work is providing a review of basic properties (density,
viscosity, thermal conductivity and heat capacity) of the most common and
referred salt mixtures. After checking data, tabulated and graphical outputs
are given in order to offer the most suitable available values to be used as
input parameters for other calculations or simulations. The reviewed values
show a general scattering in characterization, mainly in thermal properties.
This disagreement suggests that, in several cases, new studies must be started
(and even new measurement techniques should be developed) to obtain accurate
values.
