Euler equations & expansion shocks

Hi Guys,
I'm reading through some literature on transonic flows and came across a paper that says (I'm paraphrasing) that because the Euler equations do not contain a viscous term that expansion shocks are possible - whereas they are not in the Navier Stokes equations. Why is this? I asked a colleague of mine and he said it is because if you replace 'u' with '-u' in the Euler equations you get the same answer (which apparently means they're reversible). I'm afraid I don't understand the logic of this. If someone could please shed some light on this matter I'd be very grateful. T |
