I'd like to simulate a transient thermodynamic problem.
I have a heat changer with cooling water and ethanol-water alloy. I'd like to add the alloy temperature and the time contact from an excel file. The simulation is 90 minutes and I determine the temperature every minute (inside this excel).
How can I import this excel to Fluent?

Excel can be used through workbench for driving input and output parameters.
But in your case I think you will need to write UDF.
Please check customization manual in help.

I wrote a UDF, but I think it doesn't work.
I'd like 3D simulation, the start temperature is 351,3K (78°C) and then the temperature arises every sec.
Can you check it?
DEFINE_PROFILE(temp, t, i)
real time= CURRENT_TIME;
x0 = x;
F_PROFILE(f, t, i) = 351.3 + 0.01 * x0;
F_PROFILE(f, t, i) = 373;

You want the temperature to rise every second so why you are using the x-coordinate there. If your temperature profile is only time-dependent just read a transient table or transient profile for that

Thank you for your answer!
Can you write an example what you though?

here is a example for profile
((sampleprofile transient 3 0)
