Keywords: vertical axis wind turbine, double-disk momentum theory, drag coefficients of the blade profile, computer simulations, blade installation angle

Abstract

Запропоновано інженерну методику розрахунку енергетичних показників вітродвигуна з вертикальною віссю оберту, який пропонується до використання в системах автономного енергопостачання. Математична модель складена на основі дводискової імпульсної теорії. Числові дослідження проводились з уточненими значеннями аеродинамічних коефіцієнтів вибраного профілю. Складено загальний алгоритм розрахунку та отримані залежності коефіцієнта потужності від довжини хорди профілю та кута його установки.
