Hi community,
i am developing a heating device which on the one hand heats up air and on the other hand heats up a heating chamber “oven”. The heat is generated through an electrical spiral heating element with 200 Watts, that is in close contact with the “oven” and also heats up passing air.
Issue:
Whenever i want to run the simulation i have the issue of mesh quality measures, that are out of range - in my case the Non-Orthogonality. I tried to redesign the heating element as well as use volumetric refinements around the heating element to improve the mesh. I also do not want to make the mesh as fine as possible, to keep the meshing time to an acceptable level.
Can you please have a look at the project and provide me some hints on how to achieve a better mesh?
Thanks in advance and best regards
Marco
Hi,
When looking at the project, it appears that you were able to improve the non orthogonality metrics. Feel free to share an update/insights if it makes sense.
Cheers
Hi Ricardo, many thanks for your response and for taking a look into my simulation.
After another investigation of the mesh quality i ve identified further areas in my CAD that could be improved by further cleaning the Model.
Still, there might be some further issues, which your expertise might help.
I’ve build a hardware prototype and did some testing. The power source has been set to 200Watts like in the simulation. But however, the temperature at the top center of the device has been measured to be around 250°C. In the simulation the temperature at the point seems to be 100°C (see image).
Any hints, why there is such a deviation and what i can do to improve?
Best regards and many thanks in advance
Marco
