Abstract
Description
つに対する流体流を妨げるには、流体流を妨げる枝路内の慣性ポンプにより、流体の供給源として機能するリザーバからの流体流の速度の1/3である流体流の速度をもたらす。供給源リザーバから流体を受け取るn個の受取りリザーバが存在し得る他の実施態様、及び、抵抗流が存在しない場合、供給源リザーバからの流体流が交差部において異なる枝路間に等しく分かれる他の実施態様では、受取りリザーバに通じる個々の枝路における慣性ポンプを作動させることによって、存在し得る受取りリザーバのうちの特定の1つに流体流が向けられ、供給源リザーバからの流体流の速度の1/nである抵抗流がもたらされるようになっている。
