Abstract
Penelitian ini bertujuan untuk mengetahui tekanan yang diterima oleh advancing blade dan returning blade turbin Savonius blade ellips dengan mengamati aliran fluida yang melalui turbin Savonius. Blade ellips merupakan salah satu tipe blade turbin Savonius yang dikembangkan dari tipe blade konvensional. Simulasi numerik dilakukan secara dua dimensi (2D) pada aliran fluida yang bersifat incompressible, viscous dan unsteady dengan menggunakan persamaan NavierStokes. Selanjutnya diselesaikan menggunakan metode beda hingga staggered grid dan algoritma SIMPLE (Semi Implicit Method for Pressure-Linked Equation). Posisi rotor turbin Savonius disimulasikan menggunakan variasi angle of attack yaitu 45∘, 90∘, 105∘ dan 135∘. Sedangkan profil aliran fluida disimulasikan menggunakan variasi bilangan Reynolds yaitu 500, 2500 dan 5000. Hasil simulasi menyatakan bahwa perbedaan antara nilai tekanan advancing blade dan returning blade mengakibatkan turbin Savonius tipe blade ellips dapat berputar berlawanan arah jarum jam.

This study aims to determine the pressure received by the advancing and returning blades of the Savonius blade elliptical turbine by observing the fluid flow through the Savonius turbine. Elliptical blade is one type of Savonius turbine blade which was developed from the conventional blade type. Numerical simulations were carried out in two dimensions (2D) on incompressible, viscous and unsteady fluid flows using the Navier Stokes equation. Then it was solved using the staggered grid finite difference method and the SIMPLE (Semi Implicit Method for Pressure-Linked Equation) algorithm. The position of the Savonius turbine rotor is simulated using variations in angle of attack, namely 45∘, 90∘, 105∘ dan 135∘. While the fluid flow profile is simulated using a variation of Reynolds number, namely 500, 2500 and 5000. The simulation results state that the difference between the advancing blade and returning blade pressures causes the Savonius elliptical blade turbine to rotate counterclockwise.
