Abstract
The freezing rates of water droplets have been calculated. The interfacial position is specified as a power series in time, and expressions for determining the first five coefficients are given. The five–term series solution is compared with an exact numerical one for a particular case, and the agreement is within 1% during most of the freezing process. For small droplets, the solution reduces to a previously published one, and the results of experiments in which the freezing times of droplets were measured confirm this.
