For the design and optimum operation of apparatuses and plants in the field of energy technology and chemical engineering, thermodynamic properties of the corresponding working fluids (pure substances and mixtures) are required over large ranges of temperature and pressure. These properties are calculated from equations of state for whose development very accurate experimental values of the density over the whole fluid region (gases and liquids) are needed.

On this background we work on the following main research fields:

Equations of state

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

Viscometer-densimeter

Combined measurements of the viscosity and density of gases.

Software development

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

Magnetic suspension balances

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

Very accurate densimeters

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

Critical point

High precision density measurements for the investigation of the thermodynamic behaviour of fluids directly at the critical point.

pρT measurements

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

Research projects for industry

Besides our basic research, we also carry out research projects for companies if the themes fit into our research interests.
