Researches on Axial Flow Turbines

Transactions of the Japan Society of Mechanical Engineers, 1958
Ordinary, we research the characteristics of turbine blades with cascade tunnel, but we cannot expect from those researches the characteristics of turbine blades at moving state. Then, it is necessary to carry actual turbine testings to know the dynamical characteristics of turbine blades.

Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

Advanced Engineering Materials, EarlyView.
Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Experimental Investigation of Rotor-Stator Interaction in Axial-Flow Turbines and Compressors

International Journal of Rotating Machinery, 1998
Detailed results of unsteady flow measurements in a stator-rotor-stator assembly of an axial-flow turbine as well as an inlet guide vane-rotor-stator formation of an axial-flow compressor are presented in this paper.

Perspectives on the Treatment of Secondary Flows in Axial Turbines

Energy Procedia, 2017
 A review is presented of the main end-wall treatments for the secondary flows of axial turbines. This encompasses the use of axisymmetric and non-axisymmetric contoured end-walls, the use of fences, and of air injection and blowing. Experimental and numerical results show promise in all these techniques. Interest seems to be drawing towards the use of

Microstructure‐Controlled Crack Propagation and Fracture Resistance in MoSiBTiC Alloy Revealed by Multiscale Extended Finite Element Method Modeling

Advanced Engineering Materials, EarlyView.
A two‐dimensional multiscale finite element analysis framework was established for the first‐generation MoSiBTiC alloy, and the mechanical and fracture‐related parameters of the constituent phases were calibrated through experiments and simulations. The framework provides a basis for analyzing crack propagation behavior in its complex microstructure ...

Prediction of the Influence of Runner Tip Clearance on the Performance of Tubular Turbine

Journal of Marine Science and Engineering, 2022
Tubular turbine is a type of turbine with low-head. Due to the fact that the runner of a tubular turbine is of axial-flow type, there will be a certain width of blade tip between the blade and the chamber.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

On the Flow in a Water Turbine of Axial Flow Type

Transactions of the Japan Society of Mechanical Engineers, 1959
The air test of a model of the propeller turbine was performed to reconsider the methods of designing Kaplan turbines by the usual two-dimensional treatments. The performances of it, the flow conditions at the inlet and outlet of the runner and the pressure distributions on the running blades were measured to compare with the ones of two-dimensional ...
