Thermodynamic data is usually presented as a table or chart of function values for one mole of a substance (or in the case of the steam tables, one kg). A thermodynamic datafile is a set of equation parameters from which the numerical data values can be calculated. Tables and datafiles are usually presented at a standard pressure of 1 bar or 1 ...
CALPHAD had a slow start in the 60s but sophisticated thermodynamic data bank systems started to appear in the 80s and today there are several commercial products on the market, e.g. FactSage, MTDATA, PANDAT, MatCalc, JMatPro, and Thermo-Calc as well as open-sources codes such as OpenCalphad, [8] PyCalphad, and ESPEI.
The work done in a process on vapor cycles is represented by length of h, so it can be measured directly, whereas in a T–s diagram it has to be computed using thermodynamic relationship between thermodynamic properties. [1] In an isobaric process, the pressure remains constant, so the heat interaction is the change in enthalpy. [2]

Engineering Equation Solver (EES) is a commercial software package used for solution of systems of simultaneous non-linear equations.It provides many useful specialized functions and equations for the solution of thermodynamics and heat transfer problems, making it a useful and widely used program for mechanical engineers working in these fields.
Example of a Stüve diagram. A Stüve diagram is one type of thermodynamic diagram commonly used in weather analysis and forecasting. [1]This diagram has a simplicity in that it uses straight lines for the three primary variables: pressure, temperature and potential temperature.
Fundamental models refer to a family of thermodynamic models that propose a mathematical form for one of the fundamental thermodynamic properties of the system, such as Gibbs free energy or Helmholtz free energy. The core idea behind this type of thermodynamic models is that, by constructing the fundamental property, it is possible to take ...
Thermodynamic diagrams are diagrams used to represent the thermodynamic states of a material (typically fluid) and the consequences of manipulating this material. For instance, a temperature– entropy diagram ( T–s diagram ) may be used to demonstrate the behavior of a fluid as it is changed by a compressor.
