Hi can someone explain to
 
Hi

can someone explain to me what are the meaning of the term on this equation for example what does mesh.Sf actually means ,etc

linearInterpolate(rho*U) & mesh.Sf()

mesh.Sf() is the face area vec
 
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,
