Archimedes Screw Turbines (ASTs) Performance Analysis using CFD Software Based on Variation of Blades Distance and Thread Number on The Pico Hydro Powerplant

Pico hydro is a power plant that uses water as turbine propulsion can generate electricity by generator. This research will discuss the numerical analysis of effect number threads on blades. The process Computational Fluid Dynamic method and software used in ANSYS FLUENT. In variation 1 9 threaded blades, 2 6 threads, 3 4 threads. Based simulation results with blades highest torque at TSR 12 0.00984111 Nm, 0.007671419 Watt. pressure entering 0.097098 Pascal coming out 0.047954 Pascal, there total drop 0.4914 Pascal. values Archimedes three variations, it known has best performance followed other two variations.
