tfreer85 Posted May 31, 2009 Share Posted May 31, 2009 Problem: CFD Software for calculations. Must be free, opensource etc. Does anyone have any recommendations? I found this really cool website which has a lot of them (you have to scroll down a ways): http://www.imechanica.org/node/1394 Goal: To calculate the size requirements of a NACA duct split in half and still flow appx 150cfm I.E. a tradiotnal NACA duct flowing ~300cfm split in half and placed on opposite sides of the 240z hood for intake vents. I know realistically, just doing 2 traditional NACA ducts would work the best, but I'd like to go with something a little more aesthetically pleasing. Solutions: Any ideas? I have a calculator than can help me size the NACA duct, but in no particular relation to CFM. Traditional NACA Ducts: Commercial produced (not as functional) Quote Link to comment Share on other sites More sharing options...
blairjj Posted June 1, 2009 Share Posted June 1, 2009 Tyson, This one is not user friendly but it has excellent results as compared to Fluent. http://www.opencfd.co.uk/openfoam/ No windows version... Mac and Linux only. Jay Quote Link to comment Share on other sites More sharing options...
tfreer85 Posted June 1, 2009 Author Share Posted June 1, 2009 Thanks Jay! I'm okay with open source I'm running Fedora 9 right now until Fedora 11 gets released. I saw the openfoam, but it looked well pretty darn complicated but it might be worth the effort to learn it. Quote Link to comment Share on other sites More sharing options...
