Abstract
Description
도 2는 벤추리 노즐의 배기 공기 흐름이 코안다 노즐의 구동 공기 흐름을 나타내는(벤추리 노즐 외주 또는 여러 개별 노즐) 단일 진공 챔버를 구비하는 벤추리 및 코안다 원리의 조합을 도시하는 도면.
도 3은 별개의 진공 챔버(벤추리 노즐 외주 또는 여러 개별 노즐)를 구비하는 벤추리 및 베르누이 원리의 조합을 도시하는 도면.
도 4는 볼텍스 노즐과 벤추리 노즐의 조합을 구비하는 다단 배출기를 여러 방향에서 본 도면. 여기서 벤추리 노즐은 코안다 노즐로 형성될 수도 있다.
도 5는 벤추리 노즐과 코안다 노즐의 조합을 구비하는 다단 배출기를 도시하는 도면.
도 6은 외부로 가이드되는 배기 공기 흐름을 구비하는 코안다 및 베르누이 원리의 조합을 도시하는 도면.
도 7은 공기를 흡입하고 흡입력을 발생시키기 위해 내부로 가이드되는 배기 공기 흐름을 구비하는 코안다 및 베르누이 원리의 조합을 도시하는 도면.
도 8은 볼텍스 및 코안다 원리의 조합을 도시하는 도면.
