They have found the closure of the balance equations up to a finite order with respect to equilibrium; it is also possible to impose for that model the entropy and Galilean relativity principles up to whatever order with respect to equilibrium, but by using Taylor\u2019s expansion. Here, the exact solution is found, without expansions, but a bigger number of moments has to be considered and reasons will be shown suggesting that this number is at least 18.<\/jats:p>","DOI":"10.3390\/e17010214","type":"journal-article","created":{"date-parts":[[2015,1,9]],"date-time":"2015-01-09T09:49:04Z","timestamp":1420796944000},"page":"214-230","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["An 18 Moments Model for Dense Gases: Entropy and Galilean Relativity Principles without Expansions"],"prefix":"10.3390","volume":"17","author":[{"given":"M.","family":"Carrisi","sequence":"first","affiliation":[{"name":"Dipartimento di Matematica ed Informatica , Universit\u00e1 di Cagliari, Via ospedale 72, 09124 Cagliari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sebastiano","family":"Pennisi","sequence":"additional","affiliation":[{"name":"Dipartimento di Matematica ed Informatica , Universit\u00e1 di Cagliari, Via ospedale 72, 09124 Cagliari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2015,1,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"285","DOI":"10.1007\/BF00963838","article-title":"Extended Thermodynamics of Classical and Degenerate Ideal Gases","volume":"83","author":"Liu","year":"1983","journal-title":"Arch.
