tesla turbine

Hello,

Can anyone please guide me on how to make a tesla turbine from scratch.

I am actually a under-grad student of mechanical engineering right now with just enough knowledge so please make it simple if possible.

Thanks.

Hi Safeer, You can get raw disk from Hard Disk, I'd recomment desktop hardisk since they tends to be bigger (3.747") and made in aluminium most of the time, you can still use old server HDD, however, they…

You could also use CDs. They are cheap, light, and uniform.

It is also a possible solution if he is stuck with the raw material. In that case, don't try to run it above 20k RPM, because it just fragmented above 25k rpm, not to mention if you have to drill hole on them!

Team zefiros has put all their cad models as stp, you can download them. It is somewhere around their blog.

i could do that but as many people have suggested me against it and i am willing to make a lab testing setup so i would much rather not.
But thanks any ways it was helpful. Now before building the actual thing i would make a small test bed for myself.

If you want to go with HDD platters, they have surface rugosity of 2-3 angstorm, now new HDD have smoother. Tolerancing between disk is ideal and basically perfect.
Width however, might be a variable.

Typical HDD from 20GB to 1TB have disk thickness of 0.03 0.05 and 0.07" You will find mostly 0.05 and 0.07" disk, those thin disk used to be found on QUANTUM Fireball HDD, or really old HDD. I would be willing to look from 0.010 to 0.02" steel sheet if I were you.... It's less hassle to find all those scrap.

Can you afford to do metal laser cut? You will have much more flexibility then. Last time I send a quoting for a 6" disk they cost about 3$ each.

well actually since i am thinking of making it for the university so i think i have the equipment and money covered but what i am concerned about is how to control its output and input parameters electronically so that it can become a fully testable setup.
also when a certain amount of load is applied over it, it stops running as per my calculations. this is because the load is over-coming the drag produced by the flowing fluid.Can you please suggest something regarding this.

There is "that" valve that automatically open when you pass a current through it. I don't know how it's called, I've seen one though. Maybe you can make a setup to control the pressure? Otherwise, there's the foucault current for the dynamometer can work also.
