Errors in Finite Difference Solutions of Navier-Stokes Equations,
Abstract
This paper is concerned with the accuracy of numerical solutions with coarse meshes of nonlinear partial differential equations, such as the Navier-Stokes. By presuming smooth, convergent difference approximations, some first differential analyses of the computational errors are carried out and an upper error bound of 0.03 Re(Delta x-squared) is recommended for second order accurate conservative difference schemes, computed at Re(Delta x) somewhat > 2.
