- Cooling PV panels is very important to decrease the temperature of the modules's solar cell to increase the efficiency.
This video shows how adding heat sinks with ribs enhances the heat transfer process and cool the PV panel.
ANSYS FLUENT solver is used and the Solar Ray Model (Solar Load) is used for simulating the sun's rays. - วิทยาศาสตร์และเทคโนโลยี

Yunus Çengel is great academics and you analyzed it very comprehensively. Thank you so much for your time and effort.
You are very much welcome dear Murat!
@@haveanicetime Sir Im doing my thesis about solar cell exposed to solar radiation but something is getting wrong all the time. Could you please help me out and guide me? My mail is: muratsametakcan@kuark.org so that i could explain it with more detail. King regards.
Hello dear Murat, check out your e-mail. Danke!
@@haveanicetime Bitte schön, freund!
i know I am kind of randomly asking but do anybody know of a good website to watch newly released series online?
Thanks a lot for making this video.
You're very much welcome dear Ravi!
Hello sir, thank you so much for your very good videos.
You are very much welcome dear Mohsen!
Hi, thank you for your video. I'm working on a similar research, evacuated tube
solar water heater. but i have some problems with model it.
Hello dear Reza, send me the details of your model by e-mail to study them. mech.eng.ahmedmansour@gmail.com Danke!
Do you have any experience with COMSOL multiphysics modeling? If yes could you do the same problem using it? I would really appreciate if you could.
Hello dear Salman, unfortunately I have never used it because the research articles and the field I work in always use ANSYS. Danke!
hello very good video and very detailed, I'm starting to work in this area and I have doubts about how to make the geometry for each of the layers are connected.
Hello dear Thania, you're very much welcome! Watch my video about cooling the PV using fins (ribs) in ANSYS thermal found in my playlist, I have shown how I created each layer in Autodesk Inventor. Then you import it into the designmodeler. Danke!
I want to ask is there any difference in the simulation result if u assume the solar panel to be only a single surface compare to the experimental study with an actual solar panel ?
Hello, an experimental study must be carried out and you validate the numerical results against them to be sure. Danke!
Hi! I come again here just to ask about the material of the heat sink fins. Is it okay if I use Aluminium instead of Copper?
Hello dear Aqilah, you're welcome ma'am! Yes of course, it will show the effect of using Aluminum rather than copper. Danke!
Thankyou for the content!! I don't know how to take into account the joule effect or the heating that would be produced by the joule effect, would you know how? Thank you very much!
Hello, you'r welcome! Actually I validated the paper and used the inputs that were mentioned.Thanks
Hi! Thank you for this great video. I try to follow your steps and got almost the same result as yours when PV cell is suppressed. However, when I tried to combine all the PV layers & unsuppressed. My solution did not converge. & if they did converge, the results were not satisfactory. There were no temperature differences/temp.distributions. The temperature value gave 35 degrees C. I checked all of my inputs and it looks the same as in the vid.
Therefore, may I know:
1. How to get a good mesh? (since the thickness is very small. my work interface does not have relevance center option in mesh display)
2. How to named the selections of all the layers?
FYI, the design of the PV panel is (2000X1000)mm and the HSF is (1260X830)mm. The fins are at the center of the pv panel.
Also, I modeled the panel & fins together via CATIA V5. Then, imported it.
Hello dear Aqilah, it seems that you did not watch the whole video because I showed how to model the full PV (With all layers) and then after adding the heat sink. I do not know way you asked about how to create named selection for the layers because I have already shown this.
The procedure I showed is the only one that works because it guarantees no overlapping occurs. Overlapping causes divergence.
The mesh size is determined based on the y+ l calculation related to the heat transfer, Re number and turbulence mode. You find this in the references and Ansys user or theory guide.
Any part must be imported alone following the procedure of add material and add frozen. I modeled the layers in Inventor and imported every one one by one. You can model the fins in Catia or Inventor and then import it alone. After that, you generate the fluid domain around the fins like the way I showed if the fins do not have holes. If they have holes, you must create the fluid domain taking all cavities into consideration to avoid any overlapping.
That's why I drew the sketch of the fluid domain manually just to surround the fins not overlapping their solids. Do you get this?
Danke!
@@haveanicetime Yes, understood. I see now, all this while I imported all the parts together as one. Will try! Thank you so much for the response!
Hello thank you so much for this toturial, may i have your Workbench file? Im struggling with my project and its about analysis of pvt System with Fluent but its so much annoying
Hello, actually I do not share it because of the easy way to generate the CADfiles and then follow the setup procedure in ANSYS. Thanks
Hello, very interesting video. I have learned a lot through this tutorial, but I want to ask you what if you have a profile file of heat flux with (x,y,z,heat flux) that is applied to a wall and at the same time you have convective losses. Could you still use the solar load model to apply the heat to that surface? thaks in advance
Hello dear Jesse, watch my video about flux in Fluent and ansys mechanical. i talked about that. Thanks
@@haveanicetime thank you for your response, is this the video th-cam.com/video/EpUpdykYN7Y/w-d-xo.html if not can I have the exact title please?
Regarding that video, I found that the only way to apply heat flux and convection simultaneously is through the steady state thermal model.
Yes.
Hello, I am making a model of a tube from a CSP plant, the tube is exposed to the sun on one side and I have problems to locate the solar rays perpendicular to the tube, your help would be great
Hello dear Felipe, simply use the sun direction vector of the solar ray tracing to let the rays hit the tube in a perpendicular direction. Study the vectors method at 18:25 of solar ray tracing as I said in the video. Danke!
@@haveanicetime Thanks for the answer, the only problem I have is that I do not speak fluent English, so I have not been able to fully understand the ray tracing, if I had any link where I can get more information it would help me a lot,
Thank you!
@@felipeguerrero1815 Try to search for it by your language. I am only familiar with the documents I showed in the video. Danke!
Hey. Nice video. You explain very well. I am having problems with a project related to solar radiation that I am trying to simulate with Ansys Fluent. Is it possible to get your contact and ask for some help? Thank you for your attention!
Hello dear Wellington, you are welcome. Yes, here is my e-mail: mech.eng.ahmedmansour@gmail.com Danke!
My question how simulated the panel solar because you import the gemetry and how designed.
Hello dear Rabh, first we generate the CAD files using any CAD software. I use Autodesk Inventor, then we import it into ANSYS. Watch my video about cooling PV using fins (ribs) to see the geometry. Danke!
Can you give me your Gmail....
Hello dear Rabh, mech.eng.ahmedmansour@gmail.com Danke!
Hi,
How can I running long transient simulation ( more than 24h) with solar ray tracing?
Regards
Hello, actually you run the simulation at the sun hours the experiment was conducted at. Each hour has a different flux value. This will produce results at specific hours during the day light. Then you will be able to plot the curves against the hours of the day. Got it? Thanks
is it possible for you to send the file with the title 'RRIC template'?
Im trying to conduct similar simulations as well,
Thank you
Hello dear Hafiz, check out your e-mail ! Danke!
Have a nice time! thank you for your swift response, may God bless you :)
Bitte schön !
@Jonaid Ahmed Hello dear Jonaid, I only share the paper because the CAD files are easy to be generated. Check out your e-mail. Danke!

Good to have such videos sir...can u make one video on simulation of Phase change material for Photovoltaic panel with heat sink . Thanking You.
Hello dear Someshwar, you're welcome! Simply we follow the same steps and just we use the solidification and melting option then we define the properties of the PCM. That's it. Try it and if you have questions, you can ask any time. Danke!
