Ultrasonic p-wave velocities measurement in a freezing experiment of a sand + brine mixture. The calculated wave velocities using the four classic models for the system microstructure are also plotted to highlight the inadequacy of the models to describe the system. On the right, a simulation of the ice distribution (blue) in a real sand pack dataset with a freezing front from the bottom has been calculated to highlight the difference with the real data, presented in Fig. 5. |
