Eventually, I would like to numerically simulate the transient compressible flow in an axial compressor during start-up.
However, I know that this is a very challenging undertaking (to say the least).
Nonetheless I would like to ask if there are recommendations for background literature, simple models, examples, frankly anything that can get me started.
I recognize that is a potentially board question, but my "google-mojo" has left me on this one and the related Wikipedia entry is very brief.

    $\begingroup$ You might try looking at the engine simulation literature in combustion. I don't know any specific papers off the top of my head, but I know that the simulation package KIVA (in its various incarnations) has been used to simulate combustion during an engine cycle, and I assume that a moving piston simulation is the type of problem you're looking at solving. However, I wouldn't actually use KIVA, because the code is messy. $\endgroup$ – Geoff Oxberry May 24 '13 at 3:57

    $\begingroup$ @ Schorsch, try searching Masters or Doctoral theses on this topic on Google. $\endgroup$ – Subodh May 24 '13 at 8:44
  • $\begingroup$ @Subodh : Thanks. But as I said my "google-mojo" has left me on this question, hence I ask here. Can you offer any non-obvious keywords? $\endgroup$ – Schorsch May 24 '13 at 11:46
  • $\begingroup$ @GeoffOxberry : Thanks. I'll take a look at KIVA. $\endgroup$ – Schorsch May 24 '13 at 11:46

Don't know if you already found an answer yet... Try looking here for some articles here: http://scholar.google.com/scholar?q=unsteady+compressible+turbomachinery+openfoam

OpenFoam is probably the most popular open source code that could possibly be used to solve this problem. This presentation may be of help: http://www.personal.psu.edu/dab143/OFW6/Presentations/alex_wouden_slides.pdf

There is a full list of available CFD codes, just google "free cfd codes list".

  • $\begingroup$ Thanks for your answer. I will definitely take a look at OpenFoam. My question may have been unclear, but the focus should have been on transient not free cfd codes. I'll see what OpenFoam has to offer in terms of transient computations. $\endgroup$ – Schorsch Jul 31 '13 at 19:41
