Both analytical and numerical techniques show that the instantaneous cooling rate causes the interface to become increasingly concave in Temperature Gradient Technique. Dimensionless number D e = R 2 QC p C 0 /[ K ( T h ‐ T c )] is defined to express the extent in which the interface becomes more concave caused by the instantaneous cooling rate.
