Archimedes-Screw-Conveyor. Designed a machine in the shape of Archimedes' screw using Fusion 360 to remove the drain wastage from manholes. Fabricated a prototype of it and tested with sand-water mixture.
It is crucial to consider an optimization design approach to determine the optimum parameters of the Archimedes screw to increase the power output and efficiency. Different researches are ongoing to use Archimedes screw as a micro-hydropower turbine, however, the optimization of the Archimedes screw parameters are untouched yet.

Nagel and Radlik (1988) noted at their time of publication that maximum discharge rates of installed screw pump stations were on the order of 3 m3/s . However, a diesel-powered screw pumping station in Kinderdijk (Netherlands) was built more recently with four parallel, large screw pumps that are able to move roughly 4.2 …
One of the oldest machines still in use is the Archimedes screw, a device for lifting water for irrigation and drainage purposes. Its invention has traditionally been credited to Archimedes (circa 287-212 B.C.). For example, Diodorus …
Diodorus Siculus (c. first century BC), Bibliotheke, Book V, 37.3-4. . . and what is the most surprising thing of all, they [Roman slaves] draw out the water of the streams they encounter [in Spanish mines] by means of what is called by men the Egyptian screw, which was invented by Archimedes of Syracuse at the time of his visit to Egypt; and by the use of such screws they …
Now, an Archimedes screw used as a propeller has a leading edge and trailing edge where hydrodynamic effects may actually be generated, but the bit in the middle is still just a conveyor. So it may be accurate to say that part of it has an aspect ratio but a possibly large chunk of the thing may have no aspect ratio at all.
The main difference between an Olds Elevator and a Traditional Archimedes Screw is their design and function. The Olds Elevator is a type of continuous conveyor system that uses a chain of buckets to transport materials, while the Traditional Archimedes Screw is a type of pump that uses a rotating screw to move materials.
A screw conveyor :- ... Remove the outer cylinder of the Archimedes's screw, mesh a gear of proper tooth thickness with the screw & we are done. Here the screw thing is called worm. Now the reason I love it is because the worm will definitely drive the gear but the gear may or may not drive the worm depending on the design of worm.
Screw Pitch is nothing but the Pitch of the Screw Flight or Conveyor Blade. it is the pitch distance of the blade. It is denoted By P. for generating a flat pattern of screw flight or calculating blank plate diameter you have to provide this size in the input field. ...
