ANSYS 17.0 Fluent CFD - 3D Airfoil Tutorial
Рет қаралды 7
Күн бұрынFull Video Download Link: bit.ly/2LkT2mq
New tutorial in Ansys 17.0 FEA Fluent CFD of a 3D NACA 2412 airfoil using dynamically changing velocity profile along with changing angle of attack. Velocity goes from 0 to 40m/s and the angle of attack from 0deg to 40deg. We will use turbulence flow models, generate CD and CL profiles, force results and generate pressure and velocity contour plots.
We will be rendering fancy 3D animation videos in CFD-POST for post processing the FEA results, using streamlines, volumetric rendering, specular lighting, etc.

You should share more videos as this, you explain them so well, it doesn't care you charge for this. You do it so well. I wanna more videos of aerodynamics simulation please.

Thanks for the tutorial! I've search all over the internet, but your tutorial is much more comprehensive and clear! Keep up the good work! :) P.S. why did you use hex dominant instead of tetra? You mentioned adding boundary layers for more detailed mesh, but inflation can't be used with hex dominant.
@drdalyo 7 жыл бұрын
+Michael Nguyen hey thanks for the support! I used hex to save on element count in order to reduce calculation time. You could use tetra with inflation for more accuracy!

+Vitinho995 hey thanks! I havent done the math, but I would say you should use something like at least 5x the airfoil length, so 5m on all sides

Hey Good Video! I think you could have explained the udf part more. You have made us understand what the udf is doing but if you could explain it line by line like "f" is face, what each variable mean it would be helpful. - intermediate learner
@rakshitbhansali7540 7 жыл бұрын
Great video DrDalyO.. I was also interested in the part where you talk about dynamic meshing. A problem that I am interested is in oscillating the angle of attack within a certain set of values. Which UDF macro would be beneficial in achieving a rotational motion of the airfoil- DEFINE_CG_MOTION or DEFINE_ZONE_MOTION? I also know that there is a moving wall option that can be used to provide a rotational motion to the airfoil when defining boundary conditions which could be helpful in some way. Which one do you suggest?

hi！worth buying! could u please tell me why did you set the Angle and Mag(velocity) in excel the same? are there any equations describing the relationship between them?
@drdalyo 7 жыл бұрын
+CHEN CHEN there was no reason why i made the angle and magnitude the same, it was just for the tutorial to make it simple. You could change the variation of angle and magnitude as you wish. The relation only exists when expanding the magnitude into X Y components. Please see the formulas in the excel sheet
@VivekSingh-mt8ub 7 жыл бұрын
Hi! Thank you for the upload, just wanted to know, I'm working for two angle of attacks (3 and 5). Should I simply resolve components in X and Y coordinates in velocity inlet and input them, or create a UDF file for them? Also, I want to study the magnus effect on the rocket while it is following its trajectory. So, should I rotate the mesh or the body? And how to do either of that? Thank you. Excellent stuff!
