Question

Shock waves that deviate from the arbitrary angle are called_______

(a) Oblique shock

(b) Bow shock

(c) Normal shock

(d) Detonation

This question was posed to me in homework.

My doubt is from Velocity of Sound or Pressure Wave in a Fluid in portion Compressible Flow of Fluid Mechanics

Answer 1

Right choice is (a) Oblique shock

For explanation I would say: Shock waves in a flow field which are attached to a body start deviating at some arbitrary angle from the flow direction of the fluid. This shock so developed due to angle deviation is called as oblique shock.
