EXPERIMENTAL STUDY FOR AERODYNAMIC PERFORMANCE OF ULTRA-HIGHLY LOADED AXIAL TURBINE BY USING SMALL SIZED WIND TUNNEL FOR ANNULAR CASCADE : APPLICATION EFFECT OF SQUEALER TIP

open access: yes, 2023
The increase of turbine blade loading by the increase of blade turning angle is an effective method to improve the efficiency of gas turbines. However, it intensifies the secondary flows, such as passage vortex and leakage vortex. The squealer tip, which

Integrating Patient‐Reported Quality Measures in Systemic Lupus Erythematosus: Development of the American College of Rheumatology Implementation Guide

open access: yesArthritis Care &Research, EarlyView.
Objective To support high‐quality, patient‐centered care for systemic lupus erythematosus (SLE), the American College of Rheumatology (ACR) developed evidence‐based measures incorporating clinical and patient‐reported outcome measures (PROMs). Using the Consolidated Framework for Implementation Research (CFIR), we conducted semistructured interviews ...

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Effect of Turbine Blade Tip Cooling Configuration on Tip Leakage Flow and Heat Transfer

open access: yes, 2019
The pressure difference between suction and pressure sides of a turbine blade leads to the so-called phenomenon, the tip leakage flow, which most adversely affects the first-stage high- pressure (HP) turbine blade tip aerodynamics.

Flow Visualization in a Linear turbine Cascade with Tip Clearance

open access: yes, 2005
Flow visualization and heat/mass transfer measurements in a linear turbine cascade with tip clearance levels ranging from 0.60% to 6.90% of actual chord show the influence of blade tip geometry for a standard flat tip, a squealer tip and a geometry ...

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions

open access: yesAdvanced Engineering Materials, EarlyView.
This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...
