Stefan number



The Stefan number, St or Ste, is defined as the ratio of sensible heat to latent heat. It is given by the formula

Ste = \frac{Cp T}{L}

where Cp is the specific heat, T is the temperature difference between phases, and L is the latent heat of melting. It is a dimensionless parameter that is useful in analyzing a Stefan problem. The parameter was developed from Josef Stefan's calculations of the rate of phase change of water into ice on the polar ice caps.
