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

Heat 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 ...

Production of hydroxyectoine from biogas by an engineered strain of Methylomicrobium alcaliphilum using a novel Taylor‐flow bioreactor

Journal of Chemical Technology &Biotechnology, Volume 100, Issue 7, Page 1425-1433, July 2025.
Abstract BACKGROUND The production of compatible solutes, such as ectoine and hydroxyectoine, is of great interest due to their industrial and biotechnological applications. Methylomicrobium alcaliphilum was genetically engineered to replace a native gene with a heterologous one, aiming to enhance ectoine production.

Existence of a local strong solution to the beam–polymeric fluid interaction system

Mathematische Nachrichten, Volume 298, Issue 7, Page 2327-2379, July 2025.
Abstract We construct a unique local strong solution to the finitely extensible nonlinear elastic (FENE) dumbbell model of Warner‐type for an incompressible polymer fluid (described by the Navier–Stokes–Fokker–Planck equations) interacting with a flexible elastic shell.

Parameterized Local Reduced Order Model of Stimulated Volume Evolution in Reservoirs

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 10, Page 2357-2375, July 2025.
ABSTRACT Real‐time simulation of large‐scale geomechanics problems, such as hydraulic dilation stimulation, is computationally expensive as they must span multiple spatial and temporal length scales, often including nonlinearities and thermo‐hydromechanical processes.

Dragonfly‐Inspired Aerodynamics in Horizontal Axis Wind Turbines: Insights Into Fore‐Blade and Hind‐Blade Interaction Through Experimental and CFD Studies

Wind Energy, Volume 28, Issue 7, July 2025.
ABSTRACT Taking inspiration from dragonfly tandem wing aerodynamics, this study explores a novel wind turbine design featuring tandem blades. A 1‐m diameter horizontal axis wind turbine is tested in a wind tunnel at wind speeds between 4 and 12 m/s.
