CFD of Turbine Blade

[Anonymous]

Hello
I’m interested in a CFD simulation of a turbine blade with an open section at its tip. The blade rotates at 600 rpm about a center-line and the enclosure that the turbine is subjected to is a constant external pressure of .4 psia. I am interested in the pressure profile within the blade. i.e. Does the interior of the blade pressure profile increase or decrease (experience a vacuum) as it rotates about the center line axis. I’ve went through the axial turbine CFD tutorial but I’m unsure of how to define the rotating region of this scenario. Plus, there isn’t an external air (fluid) velocity entering or zero pressure exiting the free body diagram, since the turbine is within a constant .4 psia environment.

Any guidance would be appreciated.

Thanks!

Hi @Anonymous,

Thanks for reaching out to us on the forums! You can certainly model this in CFD. I have a fair amount of experience with rotating regions and turbomachinery. Feel free to look over this PPT I built a few years back for a pro bono project I was working on. We've also produced a few webinars on the topic. I did one you can reference here. Jon Wilde also did one a few years prior on the same topic. You can find it on the same youtube channel.

Thanks,
