摘要

涡轮机是一种水力发动机，能量传递是基于水的动能和势能(压力)进行的。在本文中，我们设计了螺旋涡轮机匣-叶轮组件的尺寸，几何形状的技术文件形式和其他作者的文章。该总成的CAD设计具有一定的挑战性，采用西门子的。nx软件完成。通过导入该组件，在ANSYS CFX中对流体流动进行了研究，得出了流体速度和压力场的一些结论。考虑了水轮机运行过程中可能出现的空化现象，并对空化现象的影响进行了分析。如果发现液压回路中存在蒸汽，则会产生空化，这一事实可以用蒸汽体积分数来突出显示。

SPIRAL TURBINE CASING - IMPELLER ASSEMBLY DESIGN AND FLUID FLOW ANALYSIS

Turbine is a hydraulic engine where energy transfer occurs both based on the kinetic energy and potential (pressure) of the water. In this article we have designed the Spiral Turbine Casing – Impeller assembly with dimensions, geometry from technical documentation forms and the articles of other authors. CAD design of this assembly is a challenge and was done using .NX SIEMENS. The study of the fluid flow was done with ANSYS CFX by importing this assembly, some conclusions were drawn regarding the fluid velocities and the pressure field. The cavitation phenomenon that may occur in the operation of the turbine was also taken into account and some conclusions were drawn regarding the effects of this phenomenon. If the presence of vapours in the hydraulic circuit is found, then the cavitation can develop and this fact can be highlighted with Vapour Volume Fraction.
