| Abstract: | The micro-scale freezing damage mechanism is a key factor for cryosurgery and cryopreservation of biological material. Focusing on the microscale freezing problem, a phase-field model was employed to numerically simulate the formulation of the ice crystal. The basic approach to establish the important parameters was illustrated. Finally, both process and characteristics of the two-dimensional ice crystal growth under isotropical conditions were calculated. |
