In science:

We define an equivalent LdT such that the volume change of the entire drainage system homogeneous temperature change LdT is equal to the volume change induced by the true non-homogeneous temperature field.
Effect of the volume of the drainage system on the measurement of undrained thermo-poro-elastic parameters
The comparison of the equations (23) and (24) respectively with equations (12) and (13) shows the effect of the drainage system of the triaxial cell on the measured coefficients.
Effect of the volume of the drainage system on the measurement of undrained thermo-poro-elastic parameters
By opening the valve, the fluid flows into the drainage system.
Effect of the volume of the drainage system on the measurement of undrained thermo-poro-elastic parameters
As soon as the first drop of the fluid flows out of the porous stone, the pressure/volume controller is stopped and the volume of the fluid which has filled the corresponding part of the drainage system is directly given by the volume change of the pressure/volume controller.
Effect of the volume of the drainage system on the measurement of undrained thermo-poro-elastic parameters
The compressibility of the drainage and pressure measurement systems Lc is evaluated by applying a fluid pressure and by measuring the corresponding volume change in the pressure/volume controller. A metallic sample is installed inside the cell to prevent the fluid to go out from the drainage system.

Experimental artefacts in undrained triaxial testing
Among the different parameters appearing in equations (17) to (20), the porosity f of the tested material, its drained compressibility dc and the ratio of the volume of the drainage system to the one of the tested sample, LV V are the most influent parameters.
Experimental artefacts in undrained triaxial testing
We can also see the significant effect of the volume of the drainage system on the measurement error. The measurement error for the uc is presented in Figure undrained compressibility (3) where we can observe that it is more important for low-porosity rocks and for greater volume of the drainage system.
