Stagnation pressure for attached shock

[snowman5]

Hi, does anyone know the definition of "stagnation pressure" at the tip of a slender body
with attached oblique shockwave?

Since the shockwave is completely "attached" to the pointing tip, I think that there is
no flow "behind" the shock at the tip.
So I proceed to think that the stagnation pressure at the tip should be stagnation pressure
of the freestream flow without any pressure loss from the shock.

I have been looking for the answer for days but surprisingly there is not a single source
that answers my question.

I appreciate any help.

I think that is a pretty good estimate. although, sometimes when you zoom in on the tip you still see a small "bow" wave in front of the tip. From a distance the shock wave seems attached.

I too think that you are right. the stagnation pressure of freestream will be same as that of the stagnation pressure at the tip
