Abstract:

Engines of all sorts, from steam engines to those used in nuclear power plants, require a knowledge of a the precise location of phase transition lines, b exactly what happens when a material such as steam is moved across a given phase transition line. This information is essential from the engineering point of view because only with this information can one hope to have a truly efficient engine design. Phase transitions have become an extremely active field of research because of this need. Engineers, chemists, physicists, metallurgists, and mathematicians have cooperated in a multidisciplinary effort to learn new information of this subject. These efforts can be broadly categorized as follows a studies focussed on critical point exponents describing the behavior of a single function as a single variable is changed b studies focussed on equation of state describing the behavior of a function when all thermodynamic variables are changed. The focus of this contract has been category b, equation of state. A simple example of an equation of state is provided by a simple magnet in the vicinity of the Curie temperature Tc. Author
