Multiparameter equations of state - recent trends and future challenges

The purpose of this article is to update the common knowledge on characteri stic features of empirical multiparameter equations of state, to increase t he confidence of potential users, and possibly to attract other scientists to theoretical and experimental work that is relevant for the future develo pment of these kinds of thermodynamic property models. To do so, the most i mportant features of current multiparameter equations of state and of the a lgorithms which are used to develop such formulations are briefly explained . Future challenges are outlined with regard both to the development of mul tiparameter equations of state and to the underlying experimental basis. Re levant references are. given for further studies.
