- Abstract:
- With this study it was possible for the first time to visualize local sublimation front velocities of particle beds with neutron radiography and tomography. Few theoretical studies exist on the freeze-drying behavior of particle beds, but no experimental validation of the models exists basically due to the limits of traditional measurement techniques. The study was conducted at the neutron imaging facility
