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 flow behaviour along with temperature effects inside the air, you should go with a convective heat transfer simulation. (Heat transfer only inside the fluid)
Conjugate Heat Transfer simulations should be used to simulate the heat exchange between the fluid and solid parts. (Heat transfer inside the fluid and solid).
Please make sure to refer documentation page for more information on simulation types.
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
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 application.
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 boundary condition. If yes, can you highlight which part do i need to defined the wall.
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.
In regards to your general simulation setup. As you are using the incompressible solver, please delete all solid parts or your geometry, after the creation of the flow volume. For this application we only need the flow volume.
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
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.
I would suggest you, go with the standard settings at level 5.
After creation, you can see how the quality of your mesh is and maybe further improve using these refinements.
For further information on mesh quality and refinements you can have a look at theses two articles. Mesh Quality
ooh i see, thank you very much Sir for your guidance in my project. Without your help i will be facing difficult time in doing the simulation. Good bless you and your family Sir
Hi sir, when i come back to simscale to check my simulation. it comes with this info in the event log. What should i do. i do just leave it run or how?
