I recently started getting in to the area of Fluid Dynamics. I noticed that most textbooks divide the discussion of fluid behavior into two major segments: Incompressible and Compressible. Within compressible, there is further division based on whether the velocity of the fluid flow is slower or faster than the speed of sound. Being a beginner, I am unable to get my head around how the physics of fluid flow is different if its velocity is greater than speed of sound. can someone explain what happens in this regime?
This forum is a great place to get help. Thank you Ansys for creating such a wonderful platform to encourage technical discussions!
