Micro hydropower generation in rural area is important in providing electricity especially in off-grid electricity area. This study aims to predict and harness power from micro hydropower generation through conical gravitational water vortex turbine (GWVT) via SOLIDWORKS flow simulation. Conical GWVT under study was designed as fully enclosed system with conical turbine basin. Two different turbine orientations were simulated i.e., vertical and horizontal at different blade angle designs i.e., 25°, 45°, 75°, 90°, and 120° and with different number of blades i.e., 8, 12, and 18 while forces were harnessed at tangential (z-axis) direction. The simulation results showed that it was possible to run and produce force from conical GWVT design in a fully enclosed system. It was found that vertical turbine orientation produced a slightly higher force than horizontally orientated turbine, using 12 runner blades at 90° angles where the distributed forces were 15.31N and 14.12N respectively, at tangential (z-axis) direction. The results are useful to predict turbine’s torque for small capacity micro hydropower electricity generation prior to actual conical GWVT set up, in rural area, to minimise cost implication and construction issues.</p> ER -
