The analysis of the flow-field within the rotating blades of a turbomachine is performed in a frame of reference that is stationary relative to the blades.

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 significantly more straightforward, and therefore the use of relative velocities and relative flow quantities is fundamental to the study of turbomachinery.

A special test rig was developed at “Politehnica” University of Timisoara in order to investigate different flow control techniques. Consequently, a vortex rope similar to the one developed in a Francis turbine cone at 70% partial discharge is generated in the rig’s test by: Fluid Mechanics, Thermodynamics of Turbomachinery Size: Mb Table of contents: 1.

The general purpose of rotating machines is to exchange mechanical energy with a flowing stream of fluid. The turbomachines found in airbreathing engines take many forms, such as fans, compressors, turbines, free or power turbines, and propellers.

The design of these devices is one of the most. Test results are presented comparing the aerodynamic performance of single stage centrifugal compressors with thin flat plate, low solidity vaned diffusers to conventional thin vaned diffusers.

The test data were acquired from a low Mach number process gas compressor and a high Mach number industrial air compressor.

The data are all normalized relative to baseline vaneless diffuser results. Main and secondary flows within and after the runner were analyzed, and the effects of the hub and tip clearances on the velocity fields within and after the runner were evaluated.

Operation of the turbine at flow rates that are lower than the designed rate for the corresponding propeller curve resulted in vortex breakdown and the formation of Cited by: 5.

Among them, I am familiar with the books written by. Turbomachinery, in mechanical engineering, describes machines that transfer energy between a rotor and a fluid, including both turbines and a turbine transfers energy from a fluid to a rotor, a compressor transfers energy from a rotor to a fluid.

These two types of machines are governed by the same basic relationships including Newton's second Law of Motion and Euler's pump.

The rest of the book is devoted to the analysis and design of real turbomachinery configurations and gas turbines, based on a consistent application of thermodynamic theory and a more empirical treatment of fluid dynamics that relies on the extensive use of design charts.
