Numerical Investigations of the Aerothermal Performance of Modern Turbine Blade Tip Geometries at Design and Off‐Design Conditions and Under Stationary and Moving Shroud

open access: yesHeat Transfer, Volume 54, Issue 5, Page 3193-3207, July 2025.
ABSTRACT High‐pressure turbine blade tips operate under extreme thermal stress, generating significant aerodynamic losses that must be continually optimized to improve engine efficiency and durability. This study uses computational fluid dynamics (CFD) to investigate the aerodynamic and thermal behavior of advanced turbine blade tip configurations ...

Aerodynamic Performance Investigation of a Biomimetic‐Based Small‐Scale Horizontal‐Axis Wind Turbine: An Experimental Analysis

open access: yesWind Energy, Volume 28, Issue 7, July 2025.
ABSTRACT As the demand for power increases, installing small‐scale wind turbines can be an alternative solution. However, the main challenge for their implementation is the aerodynamic noise. With a view to minimizing noise, this study focuses on the performance investigation of a small‐scale horizontal‐axis wind turbine with NACA 4412 blades inspired ...
