Line tension

The line tension ($\tau$) is attributed to the contact line ${\mathcal {L}}_{\alpha \beta \gamma }$ along which three interfaces for the three thermodynamic phases, $\alpha$, $\beta$ and $\gamma$ meet. It is defined as the line contribution to the grand potential per unit length of the contact line.
