joining the cell centers does not pass through the common face. This
indicator function marks chevron cells as 1 and every other cell as 0. A
chevron quality norm
, as defined below, is used to determine
whether a cell can be classified as a chevron cell or not. The chevron
quality norm is computed using a vector
that is projected from the face center to
the line joining the cell centers:
where:
- is the face area vector.
- is the vector from the face center to the cell center.
- is the vector connecting the two cell centers.
- is the vector from the face vertex to the face center.
- The max function, in evaluating the chevron quality norm, is taken over all the face vertices.
The chevron quality norm is:
- 1 for orthogonal cells in which the line connecting the two cell centers passes through the face centroid
- 0 when the line passes through an edge of the face
- negative when the line is outside the face.
The chevron quality indicator is marked 1 when the chevron quality norm is negative.

This is only an approximation of the actual contact time; its accuracy depends on the simulation. For example, consider a fluid rising in a vertical tube that has a decreasing cross-sectional area. When the area is initially large, the contact area multiplied by contact time is also large. At the end, the free surface of the fluid reaches the height with a small cross-sectional area. If the accumulated value of contact area multiplied by contact time is divided by the recent smaller cross-sectional area, the calculated contact time can exceed the simulation time.
