From 1975 to 2006, Prof. Dr.-Ing. Wolfgang Wagner had been the Chair of Thermodynamics. The research in these years covered the following fields:

Equations of state

Development of equations of state for pure fluid substances and mixtures (gases and liquids).

Software development

Development of software to calculate thermodynamic properties from equations of state for scientific and industrial purposes.

Very accurate densimeters

Development of density-measurement methods and design of very accurate densimeters.

pρT measurements

Measurement of the density (pρT data) of gases and liquids over wide ranges of temperature, pressure and density.

Viscometer-densimeter

Combined measurements of the viscosity and density of gases.

Magnetic suspension balances

Development of special magnetic suspension balances for the measurement of thermophysical properties, e.g. density, viscosity, adsorption, solubility, etc.

Critical point

High precision density measurements for the investigation of the thermodynamic behaviour of pure fluids in the critical region including the immediate vicinity of the critical point.

Some of these research fields are continued by the present head of the Chair of Thermodynamics, see here.

The following pages only contain details about the research fields “equations of state” and “software.”
