This paper aims at extending the code verification methodology to high-orderaccurate scheme implementations on curved wall-bounded domains as well as forrealistic turbulent flows such as the flat plate boundary layer modelled by theReynolds-averaged Navier-Stokes (RANS) equations. Two new manufacturedsolutions (MSs) are introduced with demonstrated ability to verify thetreatment of slip and no-slip boundary conditions in high-order frameworks oncurved domains. These MSs serve as well to discuss the impact of the method ofcomputation of boundary normals on the order of accuracy (OOA) of the solutionat the wall. Furthermore, two turbulent boundary layer MSs from literature,devised to mimic the genuine features of RANS-modelled flows in the vicinity ofwall, are compared in terms of their suitability to achieving high-orderaccuracy. A number of useful concepts in verification are explored throughthese cases such as the limit values of the Spalart-Allmaras (SA) turbulencemodel source terms at the wall, the verification of the modified vorticity termof the modified SA model, the grid sensitivity of wall-bounded turbulent flows,the inadequacy of substituting solution verification to code verification andthe effect of non-dimensionalization of the solution on the minimization ofiterative errors via residual convergence. In all cases, demonstrations arecarried for orders of accuracy up to the sixth.
