Design of Reliable and Efficient Banki-Type Turbines

Research output: Contribution to journalArticlepeer-review


A new shape for the external surface of the Crossflow turbine blades is proposed, whichallows for the preservation of hydraulic efficiency in spite of a significant maximum bladethickness providing mechanic robustness and reliability. The final shape of the blades is assessedusing an iterative solution for two uncoupled models: a 2D computational fluid dynamic (CFD)and a structural 3D finite element method (FEM) analysis of a single blade. Application of theproposed methodology to the design of a power recovery system (PRS) turbine, a newbackpressure Crossflow-type inline turbine for pressure regulation, and energy production in areal Sicilian site follows.
