CoolProp::SurfaceTensionCorrelation Class Reference

Detailed Description

The surface tension correlation class uses correlations for the surface tension that are all of the form.

\[ \sigma = \sum_i a_i\left(1-\frac{T}{\tilde T_c}\right)^{n_i} \]

where \( \tilde T_c \) is the critical temperature used for the correlation which is almost always equal to the critical temperature of the equation of state. Result for surface tension is in N/m
