Notes:
Two conservative versions of the recently introduced locally exact consistent upwind scheme of second order (LECUSSO-scheme) are presented which both use four points (two upstream, one downstream) and do not suffer from wiggles. Test calculations using a flow problem with an exact analytical solution show that the two schemes, called LECUSSO-C and QUICK-PLUS, are superior to the original LECUSSO-scheme and to several other standard difference schemes.
