LES of Stable Combustion and Lean Blow-out in a Mach 2 Cavity Flameeholder

This study presents high-fidelity Large Eddy Simulations (LES) of supersonic combustion in a Mach 2 cavity flameholder over the full stable fueling region from 40 to 200 slpm. The simulations employ Finite Rate Chemistry LES with the Z70 ethylene-air mechanism, the Localized Dynamic k-equation model, Partially Stirred Reactor turbulence-chemistry interaction model, conjugate heat transfer, and the

Large Eddy Simulation of Thermo-Acoustic Instabilities in Bluff-Body Stabilized Flames; A Comparison Between Jet-A and C1

Due to the threat climate change poses, the aviation industry needs to adapt. In the process to convert the aviation fleet into a more environmentally friendly fleet, using biofuels such as Sustainable Aviation Fuels as a drop-in fuel remains a promising option. To include biofuels, safety aspects need to be investigated, where combustion instabilities are important. Thermo-acoustic instabilities

Age of information in relativistic communication systems

Age of Information (AoI) is a widely used metric to quantify the freshness of updates in communication systems. Existing AoI analyses implicitly assume a shared or synchronized notion of time between transmitter and receiver, thereby neglecting distortions arising from relative motion and gravitational effects. In this paper, we investigate the impact of relativistic time dilation on information f

Design, Simulation, and Virtual Certification Assessment of medium range Aeroengine Combustor

Here we present the integrated design, high-fidelity simulation, and virtual emissioncertification of a medium-range aero-engine combustor developed within the EU-funded MYTHOS project. The objective is to establish a physics-based framework capable of predicting combustor behavior for both conventional fuels and emerging Sustainable Aviation Fuels (SAF). Starting from a 0D thermodynamic cycle, a
