Rykov V.A., Rykov S.V.
It is shown that in the considered system of equations mutually transmitting line of phase equilibrium from the triple point to the critical, the description of the curved diameter meets the model saturation line Wegner. However, unlike model Wegner, the system mutually equations leads to the structure of both vapor and liquid saturation line branch members exponent are equal to 2, where isthe critical exponent saturation line. Testing the proposed model the saturation line is made on the example of describing the saturation line of argon. It is shown that the proposed model saturation line of argon with satisfactory accuracy in the range transmitted from the triple point to a critical point.
