Aerodynamics & Fluid Mechanics • Compressible Flow & Shocks • Normal & Oblique Shock Waves
Across a normal shock wave in an ideal gas flow, which of the following properties remains strictly CONSTANT?
(A) Static pressure
(B) Stagnation pressure
(C) Stagnation temperature
(D) Static density
Answer Key:
C
Step-by-Step Verified Solution
### Solution: Since the shock process is adiabatic and no work is done on the fluid, total (stagnation) temperature $T_0$ remains strictly constant across a normal shock ($T_{01} = T_{02}$). Total pressure drops due to irreversibility/entropy generation. Correct: C.
