What an isentropic acceleration does to pressure, density and temperature
The three state ratios along an isentropic acceleration from rest, against Mach number. Pressure falls fastest, density next, temperature slowest — and the ordering is fixed by the exponents rather than being a property of any particular flow. By Mach 2 the pressure is an eighth of its stagnation value and the temperature is just over half of it.
5 essays call
isentropic-curves. The drawing above is what it returns with no arguments at all; every
call below passes it something, because a placement that passes nothing draws whichever member
of the family the generator happens to default to rather than the one its essay argues about.
It is also the blast radius. Changing isentropic-curves changes every figure listed here
at once, and on this site it may change what they assert as well as what they show —
which is what has to be rebuilt and looked at before the change is believed.
Where it is called
What each of these essays asks for instead of the defaults is on the regime index, which reads the parameters back out of the finished figures rather than out of the placements.
