| Abstract: | A series of visualization experiments were conducted to investigate the transport phenomena and interface behavior during freezing-thawing processes of typical biologic tissues. Attentions were focused on the growth of ice crystals and the advancing of the phase-change interface. The tissues were scanned by Micro-CT before freezing and after thawing to investigate the inner structures. Comparison was made to identify freezing/thawing behaviors for different tissues under various freezing conditions. Based on experimental observation, the investigation was conducted to explore the influence of moisture morphology on the freezing/thawing characteristics. |
