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.

    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 tends to be in glass/ceramic which shatters when you attempt to drill them, or the disk size is too small. So you need to check and make sure if they are in aluminium only.

     

    Further, considering you are an undergraduate student in the mech department, short answer, it behaves like an impulse turbine. If you attempt to put high pressure without nozzle, then you're turbine won't turn.

     

    Here is an outdated video of my tesla turbine using HDD. It has to use 100 PSI with massive pressure lost due to set up, in order to achieve 20k rpm with no load. Our current configuration allows to feed a pressure of 9-11 PSI and running above 25k RPM with actual load.

    But yea, and don't be cheap when you will be choosing the bearing, because they gets really hot.... and you need to pick some good quality.
