 Roe + van Albada and JST agree well on the maximum lift, and again match the results of other codes.

 Away from this critical point the lift and drag characteristics are dominated by the pressure distribution and thus the two schemes agree well.
 The only significant differences in Cf between the van Albada and Venkatakrishnan limiters are at the trailing-edges.
