Analysis of NACA Airfoil | CFD Vs Experimental | Ansys Fluent Simulation | Xdynemo

Perfect demo for beginners

I think normally the Control Volume for external flow problems will be much larger as there will be wall effects like say for example, the most tested airfoil NACA 0012, for this CFD analysis, generally 20 times of the chord in all directions and a C domain will be used for analysis, this is applicable for every airfoil. The domain cannot be small as shown in the video. Post your suggestions too.

[@Xdynemo]

You are correct. The intention behind this video is to introduce the ANSYS Fluent workbench and solver settings. As you said, there are a lot of parameters which has to be optimized for accurate results such as 1. Creating C shaped mesh 2. Choosing proper element size based on grid independence test 3. Selecting Domain dimensions based on wall effects 4. Advanced mesh settings near the Airfoil wall such as inflation, mesh refinement, etc. 5. Choosing correct solver settings based on flow geometry and the nature of the flow. And many more to discuss. We will discuss these aspects in detail in our upcoming videos. Thank you for showing interest.

Incorrect value of Re 1,02 not 1,05

Excellent Demo sir. For beginner like me. 👌Thank you.

Nyc Job Man, It So Good tutorials, i have learnt the basics of CFD

[@Zethuck]

Why do you uncheck pseudo transient exactly? And what about analysing the angle where the airfoil starts to stall?? I am trying to do that (w a proper mesh) and it is not converging

[@srushti4583]

Can you please upload a video of cfd (lift and drag) analysis of a rocket outer structure ? It will be very helpful.

[@josephwakim85]

it didn;t work in my case. i m not able to initialize the flow

[@mamadtomcat7588]

It was very helpful thank you:)

[@zo5679]

can i change it to water for the medium?

[@sanathkumarnaikl7225]

Here you have used Coupled Method, If you use SIMPLE Method u'll get the [ Lift Force - 35.814 N & Lift-Coefficient - 0.259 ] and which is more accurate values when we compare with experimental results, Because I have Performed the Simulation and i felt to comment, Hope! it Helps to others, if any mistake is there let me know

[@iamSR007]

Brother, How to use SIMPLE method instead of Coupled method?

[@sahilpatle5114]

Sir please make a video on how to insert UDF in fluent

Why meshing is taking so long?

[@ethanmax97]

it usually does, from your question I can see that you are making the mesh fine for the whole domain, which would take time unless you have better computer specifications. But to overcome this, simulators generally isolate the fine mesh about the model being analyzed and leave the system with a much coarser mesh. Of course, this solution is applicable only for simulating applications similar to the video, in some cases, you have no other choice but to wait for it to mesh. I once did a piston combustion simulation and the mesh for it took 1 day. So yeah such is the case.
