Oblique shock

Question 1

Write down the basic relations for an oblique shock

Question 2

Show that the tangential component of velocity is continuous across an oblique shock

Question 3

Is the flow after the oblique shock supersonic or subsonic?

Question 4

Under what conditions the strong oblique shock can occur

Question 5

Under what conditions the flow after an oblique shock can become subsonic

Question 6

Explain terms “weak” oblique shock and “strong” oblique shock

Question 7

What does happen if the deflection angle is greater than the maximum deflection angle for the oblique
shock for given Mach number.

Question 8

Explain the term “Mach wave” and derive the equation for the Mach angle for the flow with the Mach
number 𝑀.

Question 9

Explain why the reflection angle of a shock wave reflected from a rigid wall is not equal to the incident angle

Question 10

Explain the term slip line in application to the merging of supersonic flows at the trailing edge of an airfoil
