A robust extension to the triple plane pressure mode matching method by filtering convective perturbations

open access: yes, 2015
Time-periodic CFD simulations are widely used to investigate turbomachinery components. The triple-plane pressure mode matching method (TPP) developed by Ovenden and Rienstra extracts the acoustic part in such simulations.

Dynamic flow distortion investigation in an S-duct using DDES and SPIV data [PDF]

open access: yes, 2016
The dynamic flow distortion generated within convoluted aero-engine intakes can affect the performance and operability of the engine. There is a need for a better understanding of the main flow mechanisms which promote flow distortion at the exit of S ...

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 ...

Shrouded Wind and Water Turbine Analytical Model Extensions for Tip Gaps, Center Bodies, and Flow Blockage

open access: yesWind Energy, Volume 29, Issue 2, February 2026.
ABSTRACT This paper provides improvements to a previously presented simple, accurate, lower order analytical model for predicting the performance of horizontal‐axis shrouded turbines for a wide range of shroud airfoil shapes varying in length, camber, and thickness. The new, extended model incorporates explicit quantitative predictions of those effects

Modeling Interactions and Dynamic Saturation Processes in Karst Media

open access: yesWater Resources Research, Volume 62, Issue 2, February 2026.
Abstract The simulation of karst aquifers is highly challenging due to complex conduit‐matrix interactions. This study utilizes KarstFOAM, a high‐fidelity, physics‐based numerical model, to address these challenges. KarstFOAM integrates (a) a unified single‐domain Forchheimer–Darcy–Brinkman–Stokes (FDBS) formulation that transitions naturally across ...

Rocket plume URANS simulation using OpenFOAM

open access: yesResults in Engineering, 2019
A key aspect in the launch environment of a space vehicle is the generation and propagation of noise, due to its effect in the payload. Obtaining experimental measures is an extremely difficult, so CFD techniques appear as a useful tool to estimate both ...

Die höchsten Oxidationsstufen der Seltenerdelemente und die Probleme mit den Praseodym(+5)‐Verbindungen

open access: yesAngewandte Chemie, Volume 138, Issue 1, 2 January 2026.
Alle Seltenerdelemente bilden bekanntlich tri‐ und auch di‐valente Verbindungen. Wenige tetra‐valente Verbindungen sind auch bekannt; kürzlich wurden die ersten Moleküle und Kristalle mit Praseodym(+5) synthetisiert. Der hier definierte atomare Ionisations‐Quotient IQ legt nahe, dass Ln(+4)‐Verbindungen mit geeigneten Liganden für fast alle 4f‐Elemente

Active Fluid Gurney Flaps, Controllable Lift Enhancement Toward Wind Turbine Power Production Regulation

open access: yesWind Energy, Volume 29, Issue 1, January 2026.
ABSTRACT Meeting the rising demand for renewable energy requires innovative solutions to enhance wind power extraction, particularly given demographic and geographic constraints on wind farm deployment. Active high‐lift devices, such as the Active Fluid Gurney Flap (AFGF), offer a promising approach that can dynamically modify aerodynamic performance ...
