I am currently studying CFD and I have a question about how I should interpret the term u and dx/dt. I would like to find that out in the textbook, but I could not.
When I solve 1D Euler Equation with Mass conservation
, then I get the result
In the result I have a problem about how to interpret these two terms u and dx/dt. As I understand, both terms were the flow velocity like u=dx/dt. The fact that the meaning of these terms diverges confuses me.
Thanks for your answer in advance and have a nice weekend.
