Hello to all the researchers; I'm trying to do a simulation in Ansys Fluent in order to understand what is the thermal behavior of brake discs in a complete model of a F1 car.
The CFD setup is complete, and I also managed to make rotating all the interest parts.
My question is about the thermal transient part; given a temperature immediately after braking, how could I check how much time the disk needs to cool to reach a goal temperature?
Even knowing that the results wouldn't be perfect, for simplicity I assumed:
- All the disk "body" is at the given temperature;
- No conduction, so the only way the disk can cool down is by the air flow coming from the front of the vehicle and perturbed by the surrounding parts and from the spinning of the disk itself.
A big thank you in advance to everyone will spend time to answer.
Hi Edoardo Frinconi,
If I understand you correctly, you can monitor the temperature of the disk over time to see when it reaches that desired temperature.
Hi Ashkan Ghafari and thanks for the answer;
That's exactly what I'm looking for. Unfortunately, these are my first approaches to the program and really didn't figure out how to set this up despite the attempts.
Could you suggest me any guide, post on forum or everything in where I could find some hints?

Before starting the calculation, right-click on "report definition" and then :
New --> volume report --> volume average --> field variable : temperature - static temperature --> select disk zone --> ok.
This approach gives you the volume average of the disk temperature. If you want the temperature on any surface of the disk, you should do the following:
New --> surface report --> area weighted average --> field variable : temperature - static temperature --> select the surface --> ok.
Note: in both approaches, don't forget to turn on these options: report plot, report file, and print to console.
