Basic Surgery of the Temporal Bone,We now discuss a number of specific problems concerned with the optimization of propulsion devices. These problems are such that they can be treated by means of the theory of the previous chapter. Our considerations are directed to the determination of the shed free vorticity of the optimum propellers from which follows their bound vorticity.作者: 氣候 時(shí)間: 2025-3-22 11:15

Inversely by the law, action equals reaction, the body will exert forces on the fluid. Sometimes these force actions are accompanied by the shedding of vorticity as in the case of a lifting surface of作者: 浪費(fèi)物質(zhì) 時(shí)間: 2025-3-22 22:58 作者: Favorable 時(shí)間: 2025-3-23 05:10

The actuator surface,onfine ourselves to a more restricted definition. We will use the term actuator surface for a two dimensional region in a fluid on which an external force field is concentrated. At this surface we have to admit a possible discontinuity of the pressure or of the tangential component of the velocity field or of both.作者: adroit 時(shí)間: 2025-3-24 07:27 作者: insular 時(shí)間: 2025-3-24 12:12 作者: CHART 時(shí)間: 2025-3-24 17:51

Unsteady propulsion,al unsteady propulsion occurs in the case of the Voith-Schneider propeller (section 4.7), contra rotating propellers, the propulsion wheels of a paddle boat and the sculling by means of an oar. In nature almost all animal propulsion in water or in air is unsteady, the flapping motion of the tail of 作者: 構(gòu)成 時(shí)間: 2025-3-25 03:19 作者: DAMP 時(shí)間: 2025-3-25 10:46 作者: babble 時(shí)間: 2025-3-25 13:37 作者: Ordnance 時(shí)間: 2025-3-25 17:28

Optimization theory,ribed force action. We assume the fluid to be inviscid and incompressible. First we have to define what will be called the best way of working of a device. We restrict ourselves to the minimization of a simple cost function, namely the kinetic energy losses per unit of time.作者: EVEN 時(shí)間: 2025-3-26 00:41 作者: 檢查 時(shí)間: 2025-3-26 05:02

Further we assume the occurring Reynolds numbers to be sufficiently high such that the inertia forces dominate by far the viscous forces, therefore we take the flu作者: figment 時(shí)間: 2025-3-26 10:35 作者: Jacket 時(shí)間: 2025-3-26 13:54 作者: 發(fā)誓放棄 時(shí)間: 2025-3-26 18:32 作者: 農(nóng)學(xué) 時(shí)間: 2025-3-26 21:21 作者: 愛社交 時(shí)間: 2025-3-27 04:34 作者: 案發(fā)地點(diǎn) 時(shí)間: 2025-3-27 07:35 作者: Left-Atrium 時(shí)間: 2025-3-27 12:23
