relative vorticityとは 意味・読み方・使い方

In this method of reducing the frictional resistance of the hull 10 by discharging bubbles to the submerged surface 12 of the hull 10, a negative pressure part 41 made low in pressure relative to a gas space with the navigation of the hull 10 is formed in the water to lead gas from the gas space to the negative pressure part 41 in the water while forming water flow 40 locally large in vorticity.例文帳に追加

船体１０の没水表面１２に気泡を放出して船体の摩擦抵抗を低減する方法であって、船体１０の航行に伴って気体空間に対して低圧となる負圧箇所４１を水中に形成し、気体空間から水中の負圧箇所４１に気体を導くとともに、局所的に渦度が大きい水の流れ４０を形成する。 - 特許庁
