I used to have a CFD codes list, but I'll have to dig through my archives to see if it's still viable.
What is the particular area of interest? Thermal/heat transfer/transport or more complex, e.g. thermo-mechanical? Liquid or gas or both (two-phase)? Turbulent?
I'm sorry if I was not clear. I am a high schooler, and this is for a mandatory research project. I do not think that it would be worth the amount of money for these programs, just for this type of research project.
I am doing the project on wind turbine blade designs as a set wind speed, and wanted to use a more accurate approach for getting results, ie CFD software, rather than building a mock up model of the turbine blades by hand, and just seeing how well they physically perform.
