ANSYS Fluent Tutorial N°2 | Generic Non-Premixed Combustion Chamber Modeling in Fluent

[@ryangibson4959]

Thank you so much! I've been really struggling to find a 3D combustion example. That was very helpful.

[@hafidzazharjakaria2615]

the goated tutorial

[@hadjimimou6545]

Thanks 😊 very helpful

[@manojalvandar9810]

Great example and I need to know how to model wood as a fuel in a cookstove calorific value of (15000 KJ/Kg ) ?

[@shehzaibyk]

You can define material properties in the setup

[@GPMountain]

just a quick question, can't you simulate only a quarter of the combuster and make it symmetry? It will save 75% of the computational power.

[@shehzaibyk]

Yes

[@thibaultsangla6265]

Great video I was just wondering one thing. For the mass flow rate of the secondary air, why are you taking 5.5% of the total mass ? I understand the idea but I don’t really see where the 5.5 is coming from. Thanks for your help !

[@shehzaibyk]

Its just random value

[@michaelokolo7785]

Hi, thank you for your video. Can you help a model with 3 inlet and 3 different species for non premixed model?

[@MERABETMelissa-p7v]

Can you do as the fuel nozzle ? like the spray of a fuel nozzle in a combustion chambre ? Thank you

[@shehzaibyk]

I can't make any promise. Kindly send me your problem description at [e-mail]

[@qwefeza8654]

Appreciate for video. So I have a question, why should make boolean comand(imprint)? What means of "Injector do not have imprint"? (If no boolean comand, what happen?) Can I get this reason?

[@shehzaibyk]

Imprint allows continuous surface to be segmented so that mesh can modify its connectivity and conform it more closely to the specified geometry.

[@qwefeza8654]

@@shehzaibyk Thank you for answer! I understand the reason of it If you dont mind, i want to ask one more question (about application function) In command of boolean~imprint face, There are three options of preserve target body (For example, you take (No) and make some injectors' frozens again in your video) Then, Yes or Yes imprint options are same effect of yours? (I think yes)

[@jeffhannamen2311]

ım trying to combustion mixture h2 and methane in the combie boiler how can help me to this study ?

[@shehzaibyk]

You can repeat the same for H2 and Methane

[@sambrookes3403]

I have created a geometry very similar to this but with 1 large fuel inlet and due to the size difference is only a small gap between both inlets i get diffusion any help would be appreciated

[@shehzaibyk]

Kindly send me your problem description at [e-mail] Thanks

[@mithunalingaraj9395]

Thank you!

[@adrianprimandanu9318]

Thank you very helpful

[@noelrebusam38]

sir what if we have a solid fuel and we want to simulate combustion by injecting the oxidizer into the solid fuel using multiple ports?

[@shehzaibyk]

You can try it by modifying the material properties.

[@howardshaw1213]

Can I ask if we wantt to use the case for publication, how to cite it?

Hello! I have a question, how to change the concentration of hydrogen (for example from 10% to 50%), in the reaction 2H2 + O2 = 2H20, in Ansys Fluent, thank you in advance.

[@shehzaibyk]

You need to adjust mass fraction of species in FLUENT setup

[@edwardhuang1299]

What’s the excess air coefficient in this case?

[@shehzaibyk]

You can determine it by using the formula

[@ghij7530]

Excellent video Sir I need a way for contact with you in an important issue

[@shehzaibyk]

How can I help you? Send your queries on my email: [e-mail]

[@taiwoadedeji3232]

each time i tried to select the pattern the whole body is selected, why?

[@taiwoadedeji3232]

i got it. thanks

[@shehzaibyk]

You're welcome

[@manisek87]

outlet boundary conditions missing i think? can u share

[@shehzaibyk]

Pressure outlet

[@shitijagrawal528]

Hello sir, I want to do combustion simulation for solid fuel, it is potassium nitrate and dextrose for my project, could you please guide me regarding the same. Thank you

[@shehzaibyk]

It is a bit tricky but totally doable

[@aldevadesnandri1111]

give me a tutorial on CFD simulation, 2 type fuel for coal combustion

[@shehzaibyk]

Share the problem description

[@vedpatel4723]

hello all can someone please help me to edit material for my project i want to add methane-hydrogen and i am not getting any clue

[@shehzaibyk]

You can define in material properties
