Direct numerical simulation (DNS) has become a powerful tool in studying fundamental phenomena of laminar-turbulent transition of high-speed boundary layers. Previous DNS studies of supersonic and hypersonic boundary layer transition have been limited to perfect-gas flow over flat-plate boundary lay

Three types of difference approximations are used for solution of nonlinear boundary value problems. The schemes considered take advantage simultaneously of all grid points. Tables of coefficients used in the approximations are reported. The methods suggested are illustrated by an example.
This work investigates the mitigation and elimination of scheme-related oscillations generated in compact and classical fourth-order finite difference solutions of stiff problems, represented here by the Burgers and Reynolds equations. The regions where severe gradients are anticipated are refined b
