new turbo design
Hi everyone
Im a mechanical engineering student at sacramento state in cali. Now that im almost finished with my junior year im thinking of my senior project. I will be designing a new turbocharger. well just the impellers. here is a quick outlook and maybe you guys and gals have a lot of questions but as time goes on i will post progress.
Outlook: The turbo will have 3 or 4 impellers instead of two. i have decided on 3 for the time. basically two at the cold side of the turbo and one on the exhaust side. i will use magnets to connect and disconect these two impellers on the cold side. im doing some dynamic analysis but it gets some what complicated because i cannot simulate magnets, i just wanted to bring this out to see what you guys think. im still in the ideas and designs process.

If you really need to model a magnetic field in an FEA suite, you could try ANSYS. I've seen that done with some success. Solidworks is pretty decent only for tried-and-true part design/analysis and the like, in my experience. With more complex ideas, you're better off with a more rigorous, but perhaps less graphically pleasing, analysis engine.
I'm not quite sure what you're going to be using magnets for, but give it a shot. Perhaps I don't see what you're on about, but if you're going to use electro-magnets to "activate" your second compressor wheel, I can imagine some difficulty in targeting a spinning piece, and making sure it actually keeps spinning. That'd be a pretty nasty controller (can you find something reasonably cheap to process the feedback at a quick enough rate?), and do you really want electronics in the hot turbo?
Or maybe you were actually talking about simple magnets, and I just don't get it yet

I would suggest using neodymium magnets...
They'll need to be coated to sustain the heat. We use them in our CVD HDP and Ion Implant processes (and some others)...

The thing is that i want to use two simple magnets. neodynium would be good. Basically my design would be like this:
Have two impellers on the cold side of the turbo.
In the back of the front impeller or smaller impeller there would be a magnet.
in the front of the other larger impeller there would be another magnet.
Then as you raise the boost and the smaller impeller gives up, the two magnets would stick toghether and basically having the larger impeller work only in the high rpm range. now the difficulty would be disengaging then once low rpm is reached. what im trying to do is having almost zero lag basically like a supercharger but with the maximum efficiency achieved possible. i would not use any electronics, right now im working with a friend who understands magnetism and is helping me with this. maybe this will take a while but if anyone has any bright ideas, bring them on.
thanks
