Объектом исследования является узел системы вентиляции «вытяжное отверстие - колено». Системы вентиляции, проектируемые в зданиях различного назначения, как правило, сильно разветвлены, что приводит к значительным потерям давления, наибольшие из которых обусловлены местными сопротивлениями в элементах воздуховодной арматуры. Конструктивные особенности помещений и значительные габариты вентиляционных каналов приводят к необходимости прокладки воздуховодов с рядом установленными элементами воздуховодной арматуры. В таких случаях один элемент оказывает взаимное влияние на другой, при этом изменяются по сравнению с отдельными как коэффициенты местных сопротивлений, так и общие потери давления, что в настоящее время не учитывается при выполнении аэродинамических расчетов.
Система вентиляции, элементы воздуховодов, блок
