The turbine is used to extract energy from a flowing stream of gas and has the general characteristics introduced in section 1.3. In the axial flow turbine, the gas flows through an annular passage surrounding the rotating power output shaft, in a direction substantially parallel to the axis of the shaft.

Three-dimensional unsteady flow in an axial flow turbine
Journal of Propulsion and Power, 1985The results of an experimental program directed at understanding the unsteady mean and turbulent flow in a large-scale -l-Vi stage research turbine are presented. High response instrumentation and the phase-locked averaging data reduction technique were utilized to acquire data having high spatial and temporal resolution.

Three-dimensional flow field downstream of an axial-flow turbine rotor
34th AIAA/ASME/SAE/ASEE Joint Propulsion Conference and Exhibit, 1998A systematic and comprehensive investigation was performed to provide detailed data on the threedimensional viscous flow phenomena downstream of a modern turbine rotor and to understand the flow physics such as the origin, nature, development of wakes, secondary flow, and leakage flow.

Efficiency predictions for axial-flow turbines
International Journal of Mechanical Sciences, 1966Abstract In order to compare the relative merits of various turbine geometries, computer programmes have been written for two loss-correlations and these have been used to predict both total-to-total and total-to-static turbine efficiencies over a wide range of geometries.

Throughflow analysis of axial flow turbines
Computer Methods in Applied Mechanics and Engineering, 1983Abstract The development of a streamline curvature throughflow program to predict the flow through an axial flow turbine is described. The program can be used to predict the performance of the turbine at both design and off-design conditions. Comparison of the predictions of the program with flow measurements in a single-stage and in a two-stage ...

Axial-Flow Compressors for Gas Turbines
Journal of Fluids Engineering, 1948Abstract The development of the gas turbine during the last decade has opened a new field for compressor application. The compressor is an essential component of every gas-turbine power plant. It delivers air at some elevated pressure to the burner in sufficient quantity to maintain an efficient combustion of fuel and to cool the ...

Losses and efficiencies in axial-flow turbines
International Journal of Mechanical Sciences, 1960Abstract Calculations of efficiencies of axial-flow steam turbines have been based for many years upon experimentally determined velocity coefficients. A great amount of uncorrelated data is available. Efficiency calculations for axial-flow gas turbines have been based on loss coefficients obtained from two-dimensional cascade tests, and some ...

Axial turbines and compressors for compressible flow
1984The principal difference between axial turbines passing gases and their incompressible counterparts is the compressibility of the fluid being moved. The basic fluid mechanics is the same, and the profile behaviour information has already been covered in Chapter 3. The same can be said of compressors and blowers.

Flow Rate and Axial Gap Studies on a One-and-a-Half-Stage Axial Flow Turbine
2020Flow in a turbine stage is complex, and improving performance is a major challenge. Hence, it is still the topic of concern in the gas turbine community. Flow rate and axial gaps are of the few important parameters that affect the performance of a turbine.
