An exact non-linear Navier-Stokes compressible-flow solution for CFD code verification
An exact similarity solution of the compressible-flow NavierStokes equations is presented, which embeds supersonic, transonic, and subsonic regions. Describing the viscous and heat-conducting high-gradient flow in a shock wave, the solution accommodates non-linear temperature-dependent viscosity as well as heat-conduction coefficients and provides the variation of all the flow variables and their derivatives. Also presented are methods to obtain time-dependent and/or multi-dimensional solutions as well as verification benchmarks of increasing severity. Comparisons between the developed analytical solution and CFD solutions of the NavierStokes equations, with determination of convergence rates and orders of accuracy of these solutions, illustrate the utility of the developed exact solution for verification purposes.
