Computational Fluid Dynamics
(BMEGEÁTAG26, BMEGEÁTAM05)
2016. spring, 6th practice
Based on the learning material of Dr. Gergely Kristóf (link), created by:
• Tamás Benedek
• E-mail: benedek [at] ara.bme.hu
• Web: www.ara.bme.hu/~benedek/CFD/workbench
• If you have any problem, please don’t hesitate to ask your courseleader or me!
Agenda:
• 1st week: simulation of the flow in an orifice meter
• 2nd week: simulation of a centrifugal pump
• 3rd week: simulation of an exhaust
• 4th week: simulation of an transsonic airfoil
• 5th week: simulation of the buoyancy in a kitchen
• 6th week: individual problem solving
• 7th week: midterm exam
Main rules:
• Don’t use any special character or space! (in the file names,folder names, names of the zones and boundaries, …) TheANSYS can’t handle it.
• Working folder: C:/Work/Neptun_code (Neptun_code =your code)
• The saved files will be deleted when you turn off thecomputers of the CFD lab if you want to continue yourwork, please save it on a flash drive or send it to yourselfattached to an e-mail
