tesla turbine

Former Member

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.

    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.
