Effects of Nonuniform Blade Pitch on the Flow Through an Annular Turbine Nozzle
This paper discusses flow measurement results both upstream and downstream of a transonic annular gas turbine nozzle with a nonuniform pitch. The downstream measurements are performed in the plane where the leading edge of the rotor blade is located in ...

Transonic turbine blade cascade testing facility [PDF]
NASA LeRC has designed and constructed a new state-of-the-art test facility. This facility, the Transonic Turbine Blade Cascade, is used to evaluate the aerodynamics and heat transfer characteristics of blade geometries for future turbine applications. The facility's capabilities make it unique: no other facility of its kind can combine the high degree

On Wind Directions Estimated by Nacelle Lidar Under Different Reconstruction Methods
ABSTRACT The wind direction is closely linked to the power performance and structural loads of wind turbines. Conventional nacelle‐mounted vanes or sonic anemometers face errors associated with airflow distortions caused by turbine blades. Nacelle‐mounted lidar systems offer line‐of‐sight speed measurements from multiple positions ahead of the rotor ...

Estimating Atmospheric Turbulence Intensity From Cup Anemometer Data
Abstract Conventional cup anemometers are widely used but limited by coarse sampling in representing turbulence. To address this, we introduce a cumulative spectral density (CSD) approach that quantifies turbulence contributions from 1‐min wind speed records while explicitly accounting for aliasing.

A Conceptual Framework and Methods for Studying the Connectivity of Fishes
ABSTRACT Connectivity is a multifaceted concept that has important implications for the management and conservation of marine and freshwater fishes. We developed a conceptual framework that encompasses multiple, interrelated categories of connectedness, including landscape (e.g., structural, functional) connectivity and ecological (e.g., trophic ...

Experimental and Numerical Study of Transonic Cooled Turbine Blades
State-of-the-art gas turbines (GT) operate at high temperatures that exceed the endurance limit of the material, and therefore the turbine components are cooled by the air taken from the compressor.

Role of the modifications at the interface in glass fiber reinforced composites for damage monitoring. ABSTRACT Glass Fiber Reinforced Polymers (GFRPs) are widely used in structural applications but degrade over time due to internal damage. Structural Health Monitoring (SHM) enables early damage detection, improving reliability and reducing maintenance
