(8) which agrees with numerical data with a correlation coefficient of 0.992 for II'e > 10.
β’ Typical curves ~(/) for the case k > Oare shown in Figs. 1and
2. Figure illustrates the effect of Weber number, Fig. the effect of the 'freezing parameter' k. In Fig. , the relationship ~m(k, IVe, Re) is presented. Line a represents the quasiempirical relationship
given in [I] and recommended for large values of We and Re, and for k < 0.5. For greater values of k,as it is seen from Fig. , the time during which 2 equation ( )is valid, and for ~m < 2equation(10)can be utilized. The latter gives ~m = l for k-I =0.

where 1 m is the time of the process, and ~m = ~(tm)' As a first approximation we put in equation ( )
