Detached Eddy Simulation (DES) of a Turbulent Premixed Flame Stabilized on a Bluff Body

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 25, Issue 2, June 2025.
ABSTRACT As the demand for net‐zero emissions intensifies, low‐emission fuels (LEFs) are increasingly explored for their potential to reduce pollutants in combustion systems. The present study investigates the flame dynamics and pollutant emissions (CO and NOx) of different LEFs using detached eddy simulations (DES), a method that offers better ...

Numerical Simulations of Forced Ignition and Flame Dynamics in an Ammonia/Air Mixing Layer

open access: yesEnergies
This work explores NH3/air non-premixed combustion in a mixing layer, with the objective of quantifying the influence of key parameters on ignition and flame dynamics. A series of two-dimensional simulations were conducted with forced ignition.

Navigating human–plant reciprocity: Commercial harvesting by professionals of a medicinal plant fosters multi‐actor landscape management

open access: yesPeople and Nature, Volume 7, Issue 5, Page 1073-1085, May 2025.
Abstract Studies of human–nature relationships increasingly recognise not only nature's contributions to people but also the positive contributions of human practices to ecosystems. The concept of reciprocal contributions emphasises positive human–nature relationships. But trade‐offs between natural elements implies that human favouring of one element (
