- This video shows an approach of solving external fluid flow around an airfoil. Simple geometry, meshing, solving and post-processing are provided by ANSYS Workbench tools.
Nice work Eugene
Thanks!
Impressive work. Could you tell me what s the Re no. of the flow here? Seems like it is having Karman Street which is usually quite prominent in Laminar flow.
Hi Arijit! Thanks! Re number was around 1.4e5.
Sir my meshing process is stuck at 5%.....pls help🙏
How do I get that smooth animation i am not getting it
Hi, may I ask. Why in body sizing after select body of influence, my airfoil didn’t have a red sign like yours but mine is red sign in all boi. May you help with this? Thanks in advance.
Hi Amalia! Thanks for your question. Could you please elaborate more? I am not sure I got your point. Maybe it is just a visual trick. Does the body sizing actually work?
Regards!
@@numericalsimulationservice8107 the body sizing doesn’t work. My airfoil not detected. Btw thank you for reply my question, it means a lot. I need ur help for this :’)
Dear Amalia,
I think we can work around in some way. Maybe even we can have a brief online session where you describe issues and we can try to resolve it!
Do you know how to use this method for 2d geometry preparation for the new fluent meshing, as the option for 2d dimensions is grayed out for me after using spaceclaim
Dear Chris, could you please clarify? Do you mean ANSYS Fluent Meshing?
@@ievgennecheporenko2663 yes, the new Ansys Fluent meshing. Not the older version
@@chrisfranklinguitar7105 ANSYS Fluent Meshing does not seem to have an option to create mesh for 2D cases. I think that Workbench meshing is good enough for 2D scenarios.
The authors have two wrong scientific approaches: researching the creation of Lift force and Low pressure at upper side of the wing, relative to the ground surface and Earth. I explain the aerodynamic cavitation and existence of Lee side aerocavern, and creation of Aerodynamic force.
hi, can you post the txt file?
Greetings!
I am not sure if this is actually possible to share files here. But I think I will be able to send it by email or any other suitable way.
Regards,
Was it converged?
Hi Desmond! Sure! It has converged.
@@numericalsimulationservice8107 but I saw the residuals are still moving... Moreover, you may see vortex like structure on the tail wind side of the aerofoil, is that an indication of a non-static solution instead of a steady one?
Dear Desmond,
Residuals surely will reduce each consequent time step, because this is a transient simulation.
