average interior temperature less than the operating temperature
Dear All,
I am simulating an enclosure with one wall-constant heat flux, another wall-mixed boundary condition. I am considering s2s model and boussinesq approximation. And I have two pressure inlet and one pressure outlet. But I am getting the average interior temperature less than the operating temperature. How does it possible? Can anybody please help me? |
That is not impossible.
Temperature is determined by heat balance of the system and constitutive equation, not the operating temperature, which is only used in Boussinesq model. |
Dear xrs333
Thank you very much for your comment … In my case heat is added to the system, so ambient temperature, which is defined as operating temperature must be the minimum temperature..isn’t it? |
Ambient temperature is not necessarily defined as operating temperature.
Check for these of your model, please: partial enclosure temperature ExternalBlackBodyTemperatureMethod |
Thanks for your reply. I already checked the external black body temperature and partial enclosure temperature (although, I do not have any non-participating wall in the model). I have defined these temperatures as 300 K. However, the result for the average interior temperature is less than 300 K.
