Abstract:
The dendritic growth velocity of ice crystals is measured at undercooling levels between 5-8.5 K using a unique apparatus. The result shows that the measured velocities are smaller that the theoretical prediction based on the thermal diffusion theory with the scalling constant, Q= 0.025, which has been shown to agree with the experimental results at lower undercooling levels between 0.4 -2.5 K.
