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 ...

Microcylinder and Slot Combination for Flow Separation Control Over a Wind Turbine Airfoil

open access: yesWind Energy, Volume 28, Issue 7, July 2025.
ABSTRACT This study explores a novel passive flow control strategy combining a microcylinder and slot configuration to mitigate flow separation over an S809 wind turbine airfoil under stall conditions at a Reynolds number of 106. Numerical simulations are conducted using the Reynolds‐averaged Navier–Stokes (RANS) approach. The primary objectives are to
