While traditional approaches to prevent the carbuncle phenomenon in gasdynamics simulations increase the viscosity on entropy and shear waves nearshocks, it was quite recently suggested to instead decrease the viscosity onthe acoustic waves for low Mach numbers. The goal is to achieve what, in thispaper, we call Mach number consistency: for all waves, the numerical viscositydecreases with the same order of the Mach number when the Mach number tends tozero. We take the simple approach that was used for the proof of concepttogether with the simple model for the increased numerical viscosity on linearwaves and investigate the possibilities of combining both in an adaptive mannerwhile locally maintaining Mach number consistency.
