Bases: object

A helper class to calculate the geometry of a droplet from a set of parameters. You must specify exactly two of the following parameters:

Parameters:

  • volume (Union[Expression, int, float, None]) – The volume of the droplet

  • base_radius (Union[Expression, int, float, None]) – The base radius (contact line radius) of the droplet

  • contact_angle (Union[Expression, int, float, None]) – The contact angle of the droplet

  • apex_height (Union[Expression, int, float, None]) – The apex height of the droplet

  • curv_radius (Union[Expression, int, float, None]) – The curvature radius of the droplet

  • ambiguous_low_contact_angle (Optional[bool]) – If you set base_radius and curv_radius, you must specify if the contact angle is below or above 90°

  • evalf (bool) – If True, the result will be evaluated to a float. If False, the result will be kept as an expression

  • rivulet_instead (bool) – If True, the droplet is assumed to be a rivulet, i.e. it is just a 2d cross section of a 3d droplet. The volume is then the area of this cross section.

apex_height: Union[Expression, int, float]

The apex height of the droplet

base_radius: Union[Expression, int, float]

The base radius of the droplet

contact_angle: Union[Expression, int, float]

The contact angle of the droplet

curv_radius: Union[Expression, int, float]

The curvature radius of the droplet

volume: Union[Expression, int, float]

The volume of the droplet
