TEFIS database. Thermodynamic functions of substances
Abstract:
The TEFIS database includes data on thermo physical properties of substances under extreme conditions (high temperatures and enormous range of densities). It is based on original physical models which have been developed in M.V. Keldysh Institute of Applied Mathematics since 1960's. The first part of the database includes tables of thermodynamic functions for all elements of the periodic system. They are constructed via only two models: the generalized Saha model and the Tomas-Fermi model with quantum and exchange corrections. In this work, we briefly discuss the models, present their verification and describe the tables uploaded at the Institute server.
