Hi i currently doing a project to investigate the air flow for emboss shape coolling fin in soalr pv. However, i dont have any clue on how to simulation it using simscale as when i try to simulate it come with message "A setup with at least 28 regions is being used in a single-region analysis type. …

In case you are only interested in the flow behaviour, Incompressible simulation type is the correct approach. However, temperature dependent effects are not taken into account in Incompressible simulations such as free convection in air. (No heat transfer) In case you are only interested in the …

ooh i see so if like that , it is better for me to go for conjugate heat transfer right…since i want to analyse the effect of embossed shape fin (solid) on the temperature of solar panel

if i use convective heat transfer, i could not get the temperature of the solar panel right

I would say conjugate heat transfer is the most commonly used simulation type in electronics cooling application. You may want to follow this particular tutorial on electronics cooling by using conjugate heat transfer simulation. Step-by-step descriptions can be easily adapted to your own applicati…

alright Sir, thank you so much for your help without your guidance, i could not settle this problem related to my project. Good bless you Sir

You’re most welcome! We are happy to help. :slight_smile:

[image] Hi Sir, want to ask currently i am doing a incompressible flow simulation on the solar pv system. I am question which is after defined the inlet and outlet boundary conditon, do i need to defined the walls also for the boundary condition cause i see in the tutorial they defined the wall in…

Hello bk19110254 , as your fluid region is fully enclosed by solid walls, no boundary conditions need to be assigned. By default, SimScale will assign a no-slip wall boundary condition, which is the right assignment for this wall. So no further setup of boundary conditions is needed for this setup…

[image] Hi sir, however after i delete all the solid part still i cannot run the simulation. i cannot delete the triangular fin because that is the place where i want to analyse the flow since my project is about the flow behavior due to use for emboss fin for solar pv cooling

Hi as you are interested in the flow around these fins, only the air is needed. Therefore you have created the flow (air) volume. Thus you can also remove the fins, as these are not necessary for a single fluid simulation. [image] If you hide all the fins you can see that the fins have been sub…

sir, if i want to dicrete the mesh which setting should i chose in the mesh option
