pressure jump with 12v fan?

mavizasyon · May 25, 2021, 06:04

I have to make a steady fan simulation on fluent with pressure jump thing but I dont have geometry or spesific fan, all I have I can use 12 volt any fan on internet (simulation is needed for battery cooling) . I don't known cfd theory and fluent much so I follow videos (I am student and this simulation is necesarry in a short term) . There aren't not enough tutorial about fan simulations with pressure jump on youtube (There are videos with fan goemetry that is rotating). I saw a video that use pressure jump and extracted parametres from a fan curve. The issue was that video is endonese. I have found some fan datasheets and there are fan curves but I don't know how to exteract parametres from that curve images like video. Another video which was belong ansys itself that used a parameter which is constant for simplicity, could it be enough for cooling simulation . Can any expert say what should I do?
Edit: And also if it is enough to fan model which is non-academical what should be the fan constant parameter?

Hi

Ansys Fluent has a boundary condition for fans, where you can define the pressure jump as a function of the velocity.
Refer to:

Hope this is what you are looking for..

Reason: a question and I forget to say on fluent
