I have a mismatch in temperatures during the postprocessing of a flow analysis problem coupled with conjugate heat transfer. My problem has a cylindrical shape, with almost axial symmetry. To visualize the temperatures, I have made two cuts along X and Y planes. I also want to know the temperature in the inner part of the vessel, which is a cylinder. I expected to see exactly the same temperatures on the intersection region of the cylinder with the two planes, but this is not the case. This issue may be due to the high temperature gradient in the direction normal to the cylinder, but I am not sure.
The pictures below illustrate the problem.
Help please.
Hello AAI,
Can you double check the range of temperature for those surfaces are the same? Thanks.
I confirm that the range of temperatures is the same for the three surfaces. I am showing temperatures in the range 300-310 K. However, my problem has temperatures as high as 1200 K with a high gradient near the surface of the cylinder.
Thanks
temperature depends on the heat source. Could you share the model? thanks.
I am not sure what you mean by sharing the model. The whole model? The heat source model?
Thanks
yes, the whole model I can take a look of it. thanks.
Hi,
If the interface between fluid/solid and solid/solid are created correctly, there should be no temperature jumps.
You can send the model to ptc support and ask them forward to Simerics team. We have NDA with them. Or if you like you can send it to me privately with a simplified model. I can take a look. you can chose a file when post message. I think. Thanks.
Hi,
I have sent you a private message with my simplified model. Please check your inbox. Thanks
