To derive the Bernoulli equation, we apply the work-energy theory to the fluid in a section of a flow tube. 我們應用功能原理來(lái)導出流體在一段流管流動(dòng)的伯努利方程。
A analytical mode matching method is developed for the sound propagation through rectangular flow duct with mean flow and with lining. 流管實(shí)驗裝置是測量有流動(dòng)情況下航空發(fā)動(dòng)機消聲短艙內聲襯聲阻抗的主要裝置。
This paper examines the fluid dynamical characteristics of the duct flow in a swirlmeter by using the computational fluid dynamics approach. 本文運用計算流體動(dòng)力學(xué)方法研究旋渦進(jìn)動(dòng)流量計的流道流體動(dòng)態(tài)特性。
By controlling the piston stroke and the resistance on flow Passage,the fluid lift height and the pump speed can be controlled,thereby ideal lifting effect can be achieved. 通過(guò)控制活塞行程及泵內流道阻力，從而控制泵舉升液柱的高度和泵的運行速度，取得理想的舉升效果。
