Scaled nucleation theory for bubble nucleation of lower alkanes.

A scaling law for bubble nucleation data is developed based on the classical nucleation theory and a scaled surface tension correlation. The scaled approach is applied to a set of bubble nucleation data for lower alkanes available in the literature. The results are found to agree well also with the nucleation data for several other non-polar substances. The scaling approach is presented as a tool useful for checking the consistency of bubble nucleation data reported in the literature, and for predicting bubble nucleation for substances not measured experimentally.
