Thanks for sharing. I have some questions, 1. Why don't you use volume average for reporting the result? 2. I've followed all the steps in video, got the similar result, but as I add new plane to see in to the cross section in interior of the cell, I found that there is only heat transfer on the surface, but in the interior zone, there is no heat transfer.
Sir I have one doubt when I am setting heat generation at 4c , then before 900 sec temperature approache to around 1000 degrees centigrade but when I am Same simulation on 3C , I m getting validation result
Exceuse me, i did my assigment it's quite the familiar to ur project but it's cooling the battery bt pcm w 2 concepts air and water, when i tried to setup boundary condition the same as video but i couldnot get the same reslut like the liquid fraction, the line was not rise up, anybody can help me please
Thank you Frontier. I have a small doubt. When you specified the HTC in pcm, is it for heat transfer between cell wall and pcm ??? or it is within PCM?? or it is between and outside atmosphere?.......i guess the 3rd one. is it?
Boss we selected the heat transfer coefficient in pcm but what about the contact region???? Because we only specified the material in the contact region(all 8) but we didn't specify the heat transfer coefficient!!! Why?
I've put source term/heat generation rate (W/m3) as 45470. Rest all seems fine. I ran the same geometry and mesh with air as medium instead of PCM, it went fine.
In orevious video of yours on the same topic (ruclips.net/video/DHHnKTay5Ec/видео.html&ab_channel=FrontiersInCFD) you did not mention the n-octa as solid, but here you mentioned both solid and liquid both. Can you please explain why so?....and what difference according to you it will create? which one is more accurate?
Defining both is more accurate to do so as the wall bounday conditions are represented by solids. If you know the properties of each and every material specify all for more accurate solution
What if we want to do it with hot water, where water is outside and pcm is within the water body like pcm cylinders are inside the water tank? Can we proceed in the same manner?

This can be done in result section
Thanks for the video. Is there an option in CFD POST to visualise solidification and melting ?
No such as of now

Higher c rate means higher heat generation per unit volume check the boundary condition or else use as source term
Can u analyse pcm with liquid cooling for battery thermal management system?
Share reference paper
Thank you so much!!
You're welcome!
can you share the research paper you used for the video?
Received geometry conditions as project

Check if you have defined solid and fluid zone. As well as check for the contact region properly selected

Wall and pcm
@@FrontiersInCFDok....then what is the meaning of free stream temperature there in dialog box bcz there is no free stream motion .
Solidification to melting occurs with pcm fraction of it converted into liquid
thank you
Welcome!

Because we only specified the material in the contact region(all 8) but we didn't specify the heat transfer coefficient!!!
Why?
you can apply the boundary conditions if you see (pcm contact region trg)
i am getting temperature of above 500 celcius at cell and pcm. wondering what input wrong?
There is something wrong in boundary conditions
I've put source term/heat generation rate (W/m3) as 45470. Rest all seems fine. I ran the same geometry and mesh with air as medium instead of PCM, it went fine.
@@FrontiersInCFD I'm getting 500 Celsius at first and slowly declining as run more timesteps
change time step size
As in number of iterations per time step? Currently it's 20@@FrontiersInCFD and time step size is 1 sec
what should be the boundary conditions if air has to pass over the battery pack (IP67 Battery pack)? Anybody please
select air as working fluid during material selection define the fluid zone for air
Sir please provide the reference paper of this simulation 🙏
not a reference paper, received parameter for simulation
Is there any research paper whose geometry is related to this?? Share if any
how about the result step 😢😢
Specify Contours of temp volume rendering and velocity you can change to other parameter as well
