УРАВНЕНИЯ ЗА ДВУГАЗОВ ПОТОК В ЦИЛИНДРИЧНИ КООРДИНАТИ
Иван Антонов, Светлин Антонов, Росица Величкова, Иван Денев При изследване на броя на турбулентните потоци с аксиална симетрия е наложително да се използват уравнения за движение, пренос на топлина и примеси и за непрекъснатост в цилиндрични координати. В представената работа е направен анализ на текущите уравнения за движение в цилиндрични координати по метода на Рейнолдс, като се споменават редица разработки в България. Решението за поток с аксиална симетрия в цилиндрични координати, обаче, е по-подходящо при използване на уравнения на морските кораби, използвайки т.нар. „ефективен вискозитет“.
