Taylor solution is time-dependent and has a divergence-free velocity field. Try first a steady case, the 2D Poiseuille flow is a good bechmark to assess if your code can approach low-Mach flows.

Mach number appears intrinsically as a response between the density and pressure variation. For a low Mach number flow, some codes use pre-conditioning techniques. But I see some codes working...

That strongly depends if you are interested in testing the capability of your code in solving flows with relevant compressibility effects or not. If your code can solve low Mach flows, you can use...

If you are looking for a test of the Navier-Stokes solver that is a different issue. Furthermore, a code for compressible flows can also not work properly for the lid driven incompressible flow. ...
