cooling unit - hvac
I am currently working on my master thesis. I am simulating a laboratory with three microscopes an three associated power supplies. Each microscope and power supply has a cooling unit. In the simulation the cooling units are defined as massflow outlet (entry in the cooling unit) and massflow inlet (exit of the cooling unit).
I'd like to use a expression for a constant temperatur rise (30 K or heat flux) of the massflow inlet (exit of the cooling unit) depending (transient project) on the outlet temperature of theassociated outlet for each cooling unit.
I know there is the function of recirculation boundray conditions (https://www.learncax.com/knowledge-base/blog/by-category/cfd/recirculation-boundary-conditions-in-ansys-fluent). This function is exactly that I need, but it only works for one inlet and outlet.
My first approach to use the expression editor looks like this, but I am not experienced at using the expression synthax at all.
Thank you for the help!
Best regards !
