4 cards from this section. Quick, good the night before a test.
Define compressible flow.
Think about fluid behavior at high velocities.
What does stagnation pressure refer to?
Consider the pressure behavior in nozzle flows.
What is the condition for choked flow?
Recall the flow conditions in a nozzle.
True or False: Normal shocks are isentropic.
Consider the definition of isentropic processes.
Design a converging-diverging nozzle for a gas with a target exit Mach number of 2. Determine the area ratio required based on given inlet parameters.
Review the principles of compressible flow and how area affects velocity.
A normal shock occurs in a supersonic flow with initial conditions of M₁ = 2 and P₁ = 200 kPa. Analyze the downstream Mach number and pressure post-shock.
Use the normal shock relations to transition from supersonic to subsonic conditions.
