摘要:
The differential equations describing diffusion‐controlled growth or dissolution of an isolated sphere in an infinite body of liquid have been solved numerically assuming constant interface concentration, constant diffusivity, and constant partial specific volume. The results for dissolving spheres are presented in a way which allows change of size with time to be interpolated for wide ranges of values of the two characteristic parameters. The results for growing spheres are compared with the analytical results for growth from zero initial size.
