Sun Collector Cfd Analysis

HuseyinCan · September 2, 2020, 10:48

Hello guys nowadays i am working on a sun collector system which can be described as follows:
Sun collector part which is contain coper pipes and covered by condensers and heated by sun then this heated fluid is storaged in an insulated tank
This storaged and heated fluid than transfersit is heat to air in an another device and after this cycle ,it enters copper pipes again.
My problems are:
-I have started to work on a system which has one velocity inlet and pressure outlet and simulation results wasnot satisfying and also i couldnt achive my goal which was describing inlet with respect to outlet temp.
My question is:
-What method should i use to change inlet with respect to outlet values?

Starting from ANSYS 2019 R3 your are be able to define a function for the inlet temperature in dependence from another temperature (which you have to define first via report defintion) directly at the Boundary Condition Dialog Box.
In older Fluent versions you have to define a UDF function.
