Large Eddy Simulation of Combustion for High-Speed Airbreathing Engines

open access: yesAerospace, 2022
Large Eddy Simulation (LES) has rapidly developed into a powerful computational methodology for fluid dynamic studies, between Reynolds-Averaged Navier–Stokes (RANS) and Direct Numerical Simulation (DNS) in both accuracy and cost.

Multi-dimensional numerical simulations of type Ia supernova explosions

open access: yes, 2008
The major role type Ia supernovae play in many fields of astrophysics and in particular in cosmological distance determinations calls for self-consistent models of these events.

Surface and core detonations in rotating white dwarfs [PDF]

open access: yes, 2018
The feasibility of the double detonation mechanism—surface helium detonation followed by complete carbon detonation of the core—in a rotating white dwarf with mass ;1Me is studied using three-dimensional hydrodynamic simulations. A rapid rigid rotation

Agricultural System Resilience of Industrial Hemp: An Exploratory Value Web Analysis in the Swabian Alb

open access: yesGCB Bioenergy, Volume 18, Issue 2, February 2026.
This study assessed the industrial hemp value web resilience in the Swabian Alb, Southern Germany, where regional implementation remains limited despite hemp's bioeconomy potential. Using an indicator framework and stakeholder interviews, the research found the small, fluctuating cultivation area (e.g., 25 ha in 2024) focuses on hemp seed valorisation;

Nanodiamond–silicon nitride composites for CO2 capture technology

open access: yesInternational Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract Innovative nanodiamond (ND)–silicon nitride polymer‐derived ceramics with different concentrations of nanocarbon phase were developed within the present work and their performance as adsorbent materials for CO2 was established. The novel preparative approach consists in the synthesis of a polysilsesquiazane in the presence of different ...

Parametric Study of High Frequency Pulse Detonation Tubes [PDF]

open access: yes, 2008
This paper describes development of high frequency pulse detonation tubes similar to a small pulse detonation engine (PDE). A high-speed valve injects a charge of a mixture of fuel and air at rates of up to 1000 Hz into a constant area tube closed at one

Physics of SNeIa and Cosmology

open access: yes, 2003
We give an overview of the current understanding of Type Ia supernovae relevant for their use as cosmological distance indicators. We present the physical basis to understand their homogeneity of the observed light curves and spectra and the observed ...
