Method of Construction of Generalized Temperature Dependences of the Thermal Conductivity of Freons in Various States of Aggregation

Abstract

A method of construction of generalized dependences of the reduced thermal conductivity of Freons on their temperature on saturation lines of a liquid and a vapor and at a pressure of 0.1 MPa has been constructed, which is based on the principle of minimization of the Helmholtz free energy. Selection of the scale of the sought function and of its arguments was carried out from the characteristic-function minimum, which has permitted obtaining calculation formulas to determine the sought properties of the substances under study with an error not exceeding the experimental error.
