In-pipe hydropower vertical axis parallel turbines prototype: performance and workability testing

An improvised version of a vertical axis twin turbine in-pipe hydropower prototype, with bigger power generation (PG) channels and turbines as compared to the previous one was developed and designated as P40. The P40 was fabricated mainly using mild steel. This study aims to evaluate the flow proper...
