Turbomachinery - Wikipedia
Turbomachines are also categorized according to the type of flow. When the flow is parallel to the axis of rotation, they are called axial flow machines, and when flow is perpendicular to the axis of rotation, they are referred to as radial (or centrifugal) flow machines.
Flow through axial-flow-turbomachinery blading | Introduction …
2017年11月9日 · Velocity triangles for flow relative to blades, and Euler’s turbomachinery equation, are introduced to analyse flow through a rotor. The concepts introduced are applied to the analysis of an axial-turbomachine stage comprising a stator and a rotor, which applies to either a compressor or a turbine.
Fluid Dynamics of Axial Turbomachinery: Blade- and Stage-Level ...
The current generation of axial turbomachines is the culmination of decades of experience, and detailed understanding of the underlying flow physics has been a key factor for achieving high efficiency and reliability.
• Axial flow • Increase total pressure • permits non cavitating operation in impeller • used as boost pump, permits main pump to operate at higher speeds • e.g. LPOTP is only inducer Fluids Engineering Division Annual Summer Meeting, New Orleans, LA, 29 May 2001
In this frame of reference the flow appears as steady, whereas in the absolute frame of reference it would be unsteady. This makes any calculations signi-ficantly more straightforward, and therefore the use of relative velocities and relative flow quantities is fundamental to the study of turbomachinery.
