How to do Meshing with Inflation Layers and Air Flow over Rocket with Drag Calculation | Tutorial

In this tutorial, we will learn how to do geometry preparation for a rocket cad model and calculate drag force on the rocket. In this video the procedure of geometry preparation, meshing with inflation layers, setting up boundary conditions, and calculating drag forces has been demonstrated.

Thanks for showing and explaining all the steps

Sir, please one more video rocket cfd analysis

[jakubmarkowski]

Than you man, this video explain me everything what i want in this stage of learning

hi, thank you for the educational video for who at the beginning of the ANSYS fluent, this was so helpful. i have a question if you don't mind. can we use another visualization tool (i mean plane 1 alternatives) in order to view better streamline?

I use version 2022 R2 ansys. but I cant find 'section plane' tap in 6:00. Do you know where it is?

[shakikahnaf]

Thank you so much for the good explanation.

Keep doing such works and try to give explanation for each steps

Hello, after setting my speed according to mach 2 in the inlet in the boundary conditions section, if my rocket is at an altitude of 5000 km, what should I change and where should I do it? The reason I ask is that I cannot come to the thermal section in the inlet in the boundary conditions section and change my temperature.

Hey ! This was really helpful can you tell initial conditions that has to taken only for grid fin

Hi, Thanks for the video. While meshing I got an error : Inflation created stair step meshing at some locations. How can I fix this?

How to calculate total thickness under inflation option?

[constantincristianandrei]

Hello! Can you tell me where did you find that rocket geometry? Tks :)

[meylemen]

Hello dear friend. I have a question about CFD. I am working on a car cfd analysis on ansys. My cd results are normal but my lift coefficient is negative value. İs it normal ? How can fix it ?

[muhammedumarm]

instead of plotting recirculation.. can we calculate it??

[engineered.mechanized]

What steps to take if I would like to observe the frequency of vibrations caused by water flow over a cylindrical tube?

[muzammilraja]

It was quite helpful . . could u please upload a theoretical lecture on CFD Models like K-epsilon, k omega . . .or refer me some book to understand these models.

secondly I start the inialization as hybrid . . not standard as u did . . what's difference be two ??

[ryanbrown]

i keep getting drag force values way higher than I should. Expecting around 45 N but ansys showing a value close to 3 million. any reason you know why this is happening?

[lalithminnu]

Can you share with us your geometry model

[khaihoangcao]

Hi, I have a problem creating a rocket model. Can you give me its drawing file?
