TEFIS database. Thermodynamic functions of substances

Abstract: ТЕФИС-база данных по теплофизическим свойствам веществ при экстремальных условиях (высокие температуры и огромный диапазон плотностей). Она основана на оригинальных моделях, развивавшихся в Институте прикладной математики им. М. В. Келдыша с 1960-х годов. Первая часть базы содержит таблицы термодинамических функций всех элементов периодической системы. Они построены на основе всего двух моделейобобщенной модели Саха и модели Томаса-Ферми с квантовой и обменной поправками. В настоящей работе кратко изложены мод… Show more

“…We also used three Hugoniots from the TEFIS database [36,37] for Tb, Tm, and Ac for the comparison to the new model, as well as to the Thomas-Fermi model with corrections. We note that, although Lu is an example of the application of Tartarus to a real material considered in detail in Ref.…”
