Laboratory of Thermophysical Properties of Fluids

Laboratory of Thermophysical Properties of Fluids of CREVER has numerous experimental techniques for measuring thermophysical properties fluids, both pure as mixtures:

Vapor Pressure; Vapor-Liquid Equilibrium

Solubility; Solid-Liquid Equilibrium

Density: Molar Volume

Isobaric heat capacity

Heat of mixing, solution, dilution, reaction

Kinematic and dynamic viscosity

Thermal Conductivity

In addition to experimental measurements, the Laboratory of Thermophysical Properties of Fluids also works in the modeling of thermophysical properties of fluids, with equations of state, methods for activity coefficients, etc.

For more than fifteen years, the Laboratory of Thermophysical Properties of Fluids has mainly worked in working fluids of interest in absorption heat pumps and refrigeration. Some of these fluids are listed continued:

Ionic Liquids as absorbents

Nanofluids as an absorbent of water

Ammonia/sodium thiocyanate

Ammonia/lithium nitrate

Ammonia / lithium nitrate / Water

Ammonia / Water / sodium hydroxide

Water / lithium bromide / lithium nitrate / Cluroro lithium / lithium iodide
