/// Calculates the contact angle of a droplet with a surface |
52 |

/// using a spherical cap approximation for the droplet. |
53 |

|
|
/** The position of the spherical cap relative to the surface plane |
55 |
|
|
is determined by the center-of-mass position of the selection, |
56 |
|
|
and this method assumes a uniform density in the droplet. The |
57 |
|
|
angle of intersection between the surface of the spherical cap |
58 |
|
|
and the plane defines the contact angle, which is related to |
59 |
|
|
the center of mass height by: |
60 |
|
|
|
61 |
|
|
\f$ z_\mathrm{cm} = (2)^{-4/3} R_0 \left( |
62 |
|
|
\frac{1-\cos\theta}{2+\cos\theta}\right)^{1/3) |
63 |
|
|
\frac{3+\cos\theta}{2+\cos\theta} \f$ |
64 |
|
|
|
65 |
|
|
where \f$z_\mathrm{cm}\f$ is measured relative to the planar |
66 |
|
|
surface, and \f$R_0\f$ is the radius of the free spherical |
67 |
|
|
droplet. |
68 |
|
|
|

|
|
This method was first proposed in: |

This Analyzer requires statement of the reference height of the |
75 |

solid surface, solidZ, and \f$R_0\f$, the dropletRadius. |
