hjasak will become famous soon enough
mesh.Sf() is the face area vector and the ampersand & represents a dot-product.

Thus:

linearly interpolate rho times U from cell centres to mesh faces and calculate a dot-product of the interpolated density and velocity with the face area vector.

This gives you an approximate for the face flux.

Enjoy,

Hrv
