hello everyone

I am doing a modeling on solar air heater shown in the picture and i have some questions

it is subjected to the sun ,so I used the rosseland radiation model

i made the air inlet boundary conditions : velocity = 0.5 m/s and Temp. varies through the day time

according to this curve by using UDF.

My question is : as time passes the temp of the glass and the aluminum absorber rise as a result the air temp. rises as it moves forward in the duct

in the boundary condition of the absorber and inner glass surface - they are subjected to convection

i can approximately get the value of (h) , but how can i put the values of temp. ?


the second question : i named a surface (absorber) and gave it thickness = 0.003 m

how ansys deals with it - take that thickness up or down ? and if i want to see temperature distribution in this thickness how can i do it ?
