| Summary: | The electric energy is important part of human needs. Day by day, demand of electricity has been increases as population grows in Indonesia. The solution to reduce dependence of non-renewable energy is utilizing renewable energy such as water flow, wind, and sunlight. Pembangkit Listrik Tenaga Micro Hidro (PLTMH) is one of the best solution for utilizing renewable energy such as water flow.
PLTMH has some parts that must built with good construction so that worked with optimal performance such as runner, guide vanes, spiral houses, draft tube, coupler, generator, etc. This final project contains designing some general parts of Kaplan turbine such as draft tube, runner, spiral house, and guide vanes. The designing of these parts was simulates by Computational Fluid Dynamics (CFD) methods.
CFD methods is useful to simulate flow of water around the designed turbine blade. With this simulation methods, the optimal performance of the blades will be known so that maximum efficiency can be achieved by changing angle of runner and guide vanes blade . Based on simulation results using Fluent, the efficiency of turbine was 76% then generated power reaches 97,8 kW with 375 rpm rotation. |
