Hi, everyone. I'm trying to analyze unsteady aerodynamic analysis. The model is airfoil.

but, 1.How can I do this with "Fluent" ? (I can obtain steady result.)

2.How can I get the "unsteady pressure coefficient"?

and I'm beginer in aerodynamics, so can you recommend some reference materials(book,thesis, or website)?

Thank you in advance.

Well, unsteady analysis are always time dependent. I guess you should be having your airfoil at a reasonable angle of attack to capture those bluff body shedding.

Hope this helps!

Since you're interested, don't you think you need to do transient simulation? You can activate unsteady option in the "Define/Models/Solver" panel. Choose "Unsteady in the "Time" box, and "2nd-order implicit" in the "Unstesdy Formulation" box. Determine the time-step size so that you have a sufficient number of time steps (>50 e.g.,) per the expected period of the vortex shedding. Use the steady solution as an initial guess for your transient computation. See if there's any tutorial on unsteady flow simulation.
