| Summary: | An instrumented sample holder was developed for time-lapse
microtomography of snow samples to enable in situ nondestructive
spatial and temporal measurements under controlled advective
airflows, temperature gradients, and air humidities. The design was
aided by computational fluid dynamics simulations to evaluate the
airflow uniformity across the snow sample. Morphological and mass
transport properties were evaluated during a 4-day test run. This
instrument allows the experimental characterization of metamorphism
of snow undergoing structural changes with time. |
