ANSYS Fluent Tutorial | Conjugate Heat Transfer in a Rectangular Channel with Protrusions | Part 1/2
HTML-код
- Опубликовано: 11 сен 2024
- There is a conjugate heat transfer in a rectangular channel, in which there are some Rectangular protrusions aligned at an angle of 45 degrees to the flow velocity. Water enters at a velocity of 0.00835m/s & Temp of 295 K, there is a constant heat flux from the heater wall at a 12500 W/m^2. Find out the surface Nusselt number & Skin friction coefficient on the heater surface.
What will you learn from this tutorial?
✔How to set up a conjugate heat transfer problem in ANSYS.
✔How to mesh the geometry using sweep mesh method.
✔How to plot a reference line along any Boundary surface.
✔How to find out surface Nusselt number plot, skin friction coefficient on a protruded surface.

u are the king of Ansys
Thank you Baqer. I am just a beginner in this vast ocean.
Thanks, It really helped me out
You're welcome!
شكرا لجهودكم
You are most welcome.
Hello, Thanks for your videos, I would like to know how can I establish Heat flux as boundary condition over the solid surface without decoupling with the fluid zone? If you could help me I would appreciate it a lot. Thanks in advance.
You can out the heat flux boundary condition on the shadow wall generated. If its a heat source you can take enable the source term option to give input to the domain.
For meshing it is showing the liscence is not available for this application, what should I do?
You should open one program at a time.
when I use a circular corrugated tube 3D, How I can do this mesh?
Use adaptive sizing option with a resolution upto 7.
Great.
Thank you.
plz make Geometry of Twin screw compressor roter and casing
Plz share the details of the geometry.
my question is so simple but i can't get over with it. I am doing exact same thing with you when i am sketching (4:30 and so) but when i extrude it, it doesnt give me a body, but 2 parallel planes with 4 mm height, normal to rectangular prism
If we want to do the analysis without protrusion , can we follow the same procedure in this without the protrusion part ?
Yes, we can analyze without protrusions.
@@AnsysTutor we are having a problem with initialization , we are unable to select data file quantities. Can u help us on it ?
meshing is not updating , showing errors , how to diagonise
What is the error message.
geometry is coincidental, so meshing is not happening
When i select the rotate option the selected edges disappears why it's happening?
Do your system have any graphics card or driver?
@@AnsysTutor yes intel's integrated graphics card
How you are selecting all the solid parts and making one part in boolean operation
Boolean operation is different thing and making the solids into one part is different process. In boolean operation parts mix with other without any separating boundary wall, it becomes a single entity .
@@AnsysTutor i understood the first part can you tell me the second part in simple words
Just hold ctrl key and select all the parts , right click- make one part.
please tell which version you're using , I am using 2019 r3 and finding it difficult to follow up.
I have used Ansys version 20R1 For this tutorial.
@@AnsysTutor why is different your 2020 R1 menu image from mine?
Is inflation required around the protrusions to better estimate the heat transfer
Yes, that would be better.
I tried doing that , but there seems to be a problem with meshing , it results in a stair step mesh and I get errors on fluent about all cell zones being fluid and it gives me warning that I can't simulate using heater plate as a solid
Are you using a student version and exceeded the meshing limit?
Can i get the geometry file of this
I dont have the file. You can create it, I have shown all of the process.
Is there a specific reason you use Design modeler and not space claim? I am trying to simulate a part heating inside an auto-clave, but I cant get the coupled wall to work, it looks like there is no interaction between the solid and the fluid. (great videos by the way)
I am familiar with design modeller, thats why I use it for most of the simulation. There should not a contact region between the parts. If present then delete it to get the heat transfer in between.
can you add a tutorial of a fluid inside a box heated with a hot fluid pipe passing through the chamber

@@AnsysTutor i mean box heating with one fluid inside the box other inside the tube... pls i am facing too much problems in creating so. either 2D or 3D
