This is the first time for me here.
Consider a pipe with inlet and outlet. This outlet is open to atmosphere.
In CFD we can set inlet having variable velocity profile (e.x. parabolic profile) and I understand the flow phenomenon.
What will happen if we set inlet having variable pressure profile (e.x parabolic profile)? Can someone explain the flow behaviour?
Also, will there be difference between compressible and incompressible flow?
Thanks in advance.
PS: I mentioned CFD so that it will be easy to frame my question.
