Triangular well model
From SklogWiki
(Redirected from Equations of state for the triangular well model)
The triangular well model, proposed by T. Nagayimain one dimension
\[ \Phi_{12}\left( r \right) = \left\{ \begin{array}{ccc} \infty & ; & r \leq \sigma \\ \frac{\epsilon (r/\sigma - \lambda)}{(\lambda -1)} & ; &\sigma < r \leq \lambda \sigma \\ 0 & ; & r > \lambda \sigma \end{array} \right. \]
where \(\Phi_{12}(r)\) is the intermolecular pair potential, \(r\) is the distance \(r := |\mathbf{r}_1 - \mathbf{r}_2|\), \(\sigma\) is the hard diameter, \(\epsilon\) is the well depth and λ > 1.
