  • It's nice to see an invention made by Archimedes 2.200 years ago to still be used today

  • @sidrialgr Yes, the greeks really did their job right, so we could made modifications for the betterment :)

  • @miscbeep You did great and this comes from a Greek Mechanical/Engineer.Keep up the good work mate

  • Can you please elaborate the bearing arrangement?

  • @miscbeep, thankyou, I have modelled the screw using Solidworks, but Solidworks won't do fluid analysis, hence the use of CFX, in the process now. Of any use to anyone?

  • @studleylee Obsessive spam ? What's your problem anyway.

  • Yup, it's a turbine....miscbeep, can I ask what software you used, thinking about using Ansys CFX or Fluent for a similar problem.....and just to show I am a bit of a geek.....between 22 and 24 degrees to the horizontal plane is the optimum angle for the currently used screw turbines....;o?

  • @paul0011000 You can use Solid Works, works perfectly.

  • @railrdr523 No it's a turbine. Try searching for archimedes turbine on you tube. It's the same prinicple as the water screw pump, just operating in reverse.

    The idea is that it's on a slope in a "run of river" site like a low weir, so the top of the screw can be from 1m to 10m above the lower water level. The weight of the water coming in at the top makes the screw turn, which drives the shaft to turn the actual turbine in the machine house at the top. Very simple and elegant design.

  • Is this method of generating power better than the old methoed? By saying the old method i mean a speeing will.

  • Never mind the fact it won't work, like trying to drive a worm gear with the ring gear......

  • @dieseltwitch Before making stupid statements try doing some research. Have a look for archimedes screw turbine on you tube, there are loads of these installed all around the world, all generating power.

  • @triffiidian I have to apologize. I have never seen that type of turbine (not knowing what to call it makes it hard to look for it) and it kind of defies conventional thinking. Most turbine work on a reactive force and not on a gradational force directly at and in the turbine. (i know that pressure is a result of hight ) Now that I know they exist and do work they look like it takes a lot of work to make sure you have the pitch right. am I wrong? Again My apologize for the hasty comment.
