Archimedes Screw Design: An Analytical Model for Rapid Estimation of Archimedes Screw Geometry

In designing Archimedes screws, determination of the geometry is among the fundamental questions that may affect many aspects of the Archimedes screw powerplant. Most plants are run-of-river and highly depend on local flow duration curves that vary from river to river. An ability to rapidly produce...
