CFX simulation : boundary setting problem
I am new to ANSYS CFX and currently trying to demonstarate bubble assisted natural convection method of liquid immersion system.
My current model consists of CPU and two cold plates immersed in a cooling tank filled with fluorinert FC3283.
The tank has a nozzel inlet at the bottom face for bubbles and top face set as outlet.
CPU is set to generate 150W and Cold Plates are to absorb the whole 150W.
I was able to demonstrate natural convection and monitor flucuation of CPU temperature and fluid velocity at different air flow rate and air diameter.
However I believe the model needs something with fixed temparature as a reference value.
So I created walls around cooling tank (fluid domain) and set those calls as solid domain and isothermal at 25C.
This changed the heat transfer setting of both CPU and Cold Plates; conservative interface flux is no longer an option.
Could you please tell me how I can maintain the interface flux state of CPU and Cold Plates while adding an isothermal solid domain.
Thank you very much for your time and help in advance.
