本文考虑了一类的可压缩Navier-Stokes方程的解
In this paper we consider the solution of the compressible Navier-Stokes equations for a class of
laminar airfoil flows. The principal objective of this paper is to demonstrate that members of this
class of laminar flows have steady-state solutions. These laminar airfoil flow cases are often used to
evaluate accuracy, stability and convergence of numerical solution algorithms for the Navier-Stokes
equations. In recent years, such flows have also been used as test cases for high-order numerical
schemes. While generally consistent steady-state solutions have been obtained for these flows using
higher order schemes, a number of results have been published with various solutions, including
unsteady ones. We demonstrate with two different numerical methods and a range of meshes with
a maximum density that exceeds 8 × 10^6 grid points that steady-state solutions are obtained. Furthermore,
numerical evidence is presented that even when solving the equations with an unsteady
algorithm, one obtains steady-state solutions.
