A Rationalised CFD Design Methodology for Turgo Turbines to Enable Local Manufacture in the Global South

In the Global South, pico- and micro-hydropower turbines are often made by local workshops. Despite several advantageous features, e.g., a high power density capacity to handle silt, there is no commonly available Turgo turbine design appropriate for manufacture. Technological developments including internet, CAD, additive manufacturing increase opportunity precisely transfer designs around world. Consequently, improvements can be shared digitally used manufacturers in their context. this paper, rationalised CFD approach was guide simple changes that improve efficiency of blade. The typical industry Nepal rationalise variation potential changes. Using geometry operational parameters from an existing as benchmark, two-blade, homogenous, multiphase model developed run using commercial code ANSYS CFX. Initially, it identified jet aim position had significant effect on efficiency. A experiments’ subsequent analysis numerical visual results were make resulted improvement 69% 81%. maintained profile blade, ensuring resulting manufacture workshop.
