Abstract

In this study, a theoretical prediction model of mixed molten salt electrical conductivity was proposed based on the theory of heat generation by ion friction under an AC electric field, and a set of molten salt electrical conductivity measurement devices was designed to analyze the electrical conductivity of Solar salt, Hitec salt and Hitec XL salt. The results show that the mean absolute percentage error （MAPE） values between the theoretically predicted values and experimentally measured values of electrically conductivity for three types of mixed molten salts are 11.646%, 5.473%, and 3.419%, respectively. The trends of theoretical predicted values and experimental measured values are consistent, confirming the accuracy of the proposed theoretical prediction model.
