how to tell the difference between expansion wave and shock wave by looking at a picture of supersonic objects. I had this doubt in my mind for a long time
Across a shock wave, the Mach number decreases, the static pressure increases, and there is a loss of total pressure because the process is irreversible. Through an expansion fan, the Mach number increases, the static pressure decreases and the total pressure remains constant. The image of the object along with the schlieren will give a better idea as it is an expansion process and the discontinuities are multiple.
What can be a better explanation of Mach number than this video ! Take a bow Dr. Sandeep !
Thanks a lot Pravin
Fantastic video. Great explanation. Connecting real-world examples to equations brings a lot of clarity.
Knowledge + Experience + Skill + Passion = FlowThermolab. Great effort sir.
So nice of you and thanks alot Trilok.
very informative video, keep it up
Great video!
Thanks Maria
Proud of you happy to see you Sandeep .. 👍
Thank you Amiya
Great Explanation
Beautifully explained. Awesome Dr. Sandeep.
