Shock‐Assisted Flow Control System in Convergent‐Divergent Nozzle: A Numerical Study on Unconventional Protuberance With Different Geometry

open access: yesEngineering Reports, Volume 8, Issue 5, May 2026.
A numerical investigation using 3D RANS simulations demonstrates significant effects of protuberance geometry—cubic, cylindrical, spherical, and conical—on shock‐induced thrust vectoring in supersonic nozzles. Cubic protuberances provide the maximum jet deflection (˜2°) with negligible thrust reduction.

A comparison study on the capabilities of turbulence models and density models of CFD on realistic terrain

open access: yesMeteorologische Zeitschrift, 2018
Two groups of numerical tests were carried out in the mountainous area adjacent to the Hong Kong International Airport (HKIA) in order to test the wind field simulation capability of computational fluid dynamics (CFD) over realistic complex terrain.

Impacts of Blade Camber on Cross‐Flow Turbine Performance and Loading

open access: yesWind Energy, Volume 29, Issue 5, May 2026.
ABSTRACT Cross‐flow turbines show promise for renewable energy generation from wind and tidal sources. The rotating reference frame of cross‐flow turbine blades results in virtual camber and incidence due to streamline curvature, altering the lift, drag, and pitching moment of the blades. Adding geometric camber is therefore likely to alter performance

Assessment of URANS approach for predicting twin impinging jets in a cross-flow [PDF]

open access: yes, 2012
A very complex flow field is present when a vertical/short\ud take-off and landing (VSTOL) aircraft is operating in ground\ud effect. One major concern for this kind of aircraft in ground\ud effect is the possibility of ingestion of hot gases from the ...

Performance and Health Status of Juvenile Largemouth Bass (Micropterus nigricans) Fed Inclusions of Enzyme‐Treated and Low‐Oligosaccharide Soy Proteins

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Plant‐based proteins, such as soybean meal (SBM), have shown promising results in cultured species but also present challenges due to their nutrient composition and inherent antinutritional factors. This study investigated how the replacement of solvent‐extracted SBM with low oligosaccharide soybean meal (LSBM) or enzyme‐treated soybean meal ...

Salt forms of a thioamide: protonation of 1‐(2,6‐dimethylphenyl)thiourea

open access: yesActa Crystallographica Section C, Volume 82, Issue 3, Page 129-137, March 2026.
Treating the thioamide 1‐(2,6‐dimethylphenyl)thiourea (DMPT) with concentrated aqueous strong acids gave three salt forms with protonation at the thioamide S atom. Protonation causes lengthening of the C=S bond and shortening of the C—N bonds in effects similar to those seen when amides are protonated at the O atom.Treating the thioamide 1‐(2,6 ...

Antibody‐Targeted Artificial T Cell and Natural Killer Cell Derived Vesicles for Cancer Immunotherapy

open access: yesJournal of Extracellular Vesicles, Volume 15, Issue 2, February 2026.
ABSTRACT T cell and NK92 cell‐derived extracellular vesicles or artificial cell‐derived vesicles (ACDVs) exhibit anti‐cancer effects through inherited cytotoxic proteins like perforin and granzyme or transmembrane receptors like FasL and TRAIL. The anti‐cancer potential of artificial T and NK vesicles has been improved by attaching targeting moieties ...
