Expansion
The desired gain in technical work is also obtained in processes occurring nearly simultaneously. On the one hand, the pressure energy of the medium is partially changed into kinetic energy (change of state from 1 to 2) in the converging blade channels or volute. This, as well as the remaining pressure energy, is now converted in the rotor into mechanical work (change of state from 2 to 3) via flowdeflection and further pressure reduction (actio et reactio). These changes of state can again be described using the first law of thermodynamics for open systems (Eq. (5.1)). For the conversion of pressure energy into kinetic energy (1–2) the following applies:
5.6
For the conversion of the kinetic energy and the remaining pressure energy (enthalpy) into mechanical work (2–3) the following applies:

Generally, the reverse process – accelerated flow – is easier to comprehend. Here, in accordance with the law of energy conservation, pressure is co

预期在技术上也获得了几乎同时发生的过程。另一方面,压力能量的转换成动能是部分(状态变化从1到2)在收敛叶片通道或蜗壳。这个,以及其余的压力,现在是能量转换成机械转子状态变化(从2 - 3)通过flowdeflection和进一步的压降(行动),具有等。这些变化的状态可以描述使用第一的热力学第二定律为开放系统(Eq。(51))。转换的压力能量进入动能(1 - 2)以下的应用。

一般来说,这个过程-加速流动——更容易理解。在这里,依照法律规定,对节能、压力转化为速度(转化成动力的潜在能量流动压力能量)。讨论了燃气轮机和它的特殊属性将会继续在深度上。5.4.2教派。
