In the laboratory for fluid physics, various devices are used to determine the properties of geothermal fluids: density, viscosity, electrical conductivity, thermal conductivity, heat capacity, sonic velocity.

The lab is a facility maintained by the working group ‘Exploration of Thermal Geosystems’ of section 4.3. The lab produces data that are part of projects related to the analysis of the Earth temperature field. We measure thermal conductivity (TC), thermal diffusivity (TD) or volumetric heat capacity (RHOC) of dry and saturated rocks or geomaterials under ambient laboratory or in situ temperature conditions. The following devices are available for measurements:

• Thermal conductivity …
