Abstract

Bu çalışmada, son yıllarda sıklıkla araştırma konusu olmuş rüzgâr türbini kanat profili NREL S826’ nın açık kaynak kodlu hesaplamalı akışkanlar dinamiği (HAD) yazılımı OpenFOAM ile aerodinamik incelemesi yapılmıştır. İki boyutlu akış alanının çözümünde k-ω SST ve Langtry-Menter’ in Transitional SST (γ-〖R ̃e〗_θt) modeli kullanılırken, üç boyutlu analizlerde Transition SST (γ-〖R ̃e〗_θt) türbülans modeli kullanılmıştır. Yapılan bütün analizler zamana bağlı olup basınca dayalı yarı kapalı hibrit bir çözücü olan pimpleCentralFoam ile çözülmüştür. Elde edilen veriler deneysel çalışmalarla karşılaştırılarak detaylı bir şekilde incelenmiştir.
