Time-stable high-order finite difference methods for overset grids
… method uses interface treatments based on the simultaneous approximation term penalty method, and derivative approximations that satisfy the summation-by-parts property. Two cases of the method are analyzed. In the first case, no artificial dissipation is used and an eigenvalue analysis of the …

A provably stable and high-order accurate finite difference approximation for the incompressible boundary layer equations
… Stable and High-Order Accurate Finite Difference Approximation for the Incompressible Boundary Layer Equations Mojalefa Prince Nchupang In recent years, there has been considerable interest in numerical simulations of incompress-ible flows due to their numerous industrial applications. These …

An exact and consistent adjoint method for high-fidelity discretization of the compressible flow equations
… represent its smaller scales will amplify any approximation errors made in the adjoint formulation. Formulating a practical exact adjoint that avoids such errors is especially challenging if it is to be compatible with state-of-the-art simulation methods used for the turbulent flow itself. …
