Turbine Cooling with Point Sources

samsteak · July 6, 2016, 12:57

Hi All,

I have been using point sources to model some film cooling in an axial turbine. I had success setting this up and running it, my problem is that it takes a very long time to create all these points and populate the necessary data fields. We are talking about airfoils with anywhere between 50 - 200 individual cooling holes, so this can get quite cumbersome, especially if changes need to be made. I was wondering is there was some way to import this information from external text files or tables using some sort of journaling or scripting technique? Any advice is greatly appreciated.

Thanks.

It would be good to contact ANSYS support for advice on this application. There are multiple approaches for modeling cooling holes. Using sources there are two possible approaches: point sources, or boundary sources.

The numerical details between point sources, and boundary sources are significant enough to consider evaluating them separately. However, using boundary sources, you can use profile files (.csv) and the setup is more convenient.

Hope the above helps,
