ABSTRAK

Pneumatic wave energy converter WEC merupakan salah satu sistem pembangkit tenaga listrik yang mampu memanfaatkan sumber energi gelombang laut sebagai sumber energi yang dapat diperbaharui dengan menggunakan fuida udara bertekanan untuk menggerakkan turbin. Sistem turbin digunakan mengubah energi yang dimiliki aliran fluida udara yang dihasilkan oleh nozzle menjadi energi mekanik untuk memutar rotor. Analisa ini ditujukan untuk mengetahui karakteristik aliran udara pada sudu-sudu turbin dan mengetahui unjuk kerja sistem turbin udara. Untuk dapat melakukan analisa ini dibutuhkan tahapan-tahapan yaitu membuat model nozzle dan model nozzle blade yang kemudian dilakukan simulasi terhadap model tersebut dengan menggunakan program computational fluid dynamic. Analisa dilakukan dengan cara memvariasikan tekanan udara yaitu 3 bar 2.9 bar 2.8 bar 2.6 bar 2.5 bar 2.4 bar 2.3 bar 2.1 bar 2 bar 1.9 bar 1.8 bar 1.7 bar 1.6 bar 1.5 bar 1.4 bar. Simulasi dilakukan dengan menggunakan ANSYS CFD Code dimana didapatkan hasil dan analisa yaitu effisiensi rata-rata turbin sebesar 0849 daya maksimum yang dihasilkan turbin 1897 kW RPM maksimum 360401 RPM.


ABSTRACT

Pneumatic wave energy converter WEC is one of the power plant system that can utilize sea wave energy as a source of renewable energy using fluid of pressurized air to drive turbine. Turbine system is used to change the energy of the fluid flow of air produced by the nozzle into mechanical energy to rotate the rotor. This analysis to know the characteristic of air flow in the turbine blades and to know the performance of the air turbine system. This analysis required stages to make model of nozzle and nozzle blade models and then made simulations of that model using computational fluid dynamic program. Analysis by varying the air pressure 3 bar 2.9 bar 2.8 bar 2.6 bar 2.5 bar 2.4 bar 2.3 bar 2.1 bar 2 bar 1.9 bar 1.8 bar 1.7 bar 1.6 bar 1.5 bar 1.4 bar. Simulations performed using ANSYS CFD Code and resulted the average coefficient velocity of blade is 0846 maximum power of turbine is 1897 kW and maximum RPM is 360401 RPM.
