On the convergence rates of energy-stable finite-difference schemes
Journal of Computational Physics, 2019 We consider constant-coefficient initial-boundary value problems, with a first or second derivative in time and a highest spatial derivative of order q, and their semi-discrete finite difference approximations.

The standard upwind compact difference schemes for incompressible flow simulations
, 2016 Compact difference schemes have been used extensively for solving the incompressible Navier-Stokes equations. However, the earlier formulations of the schemes are of central type (called central compact schemes, CCS), which are dispersive and susceptible
