Verification and Validation of a Low-Mach-Number Large-Eddy Simulation Code against Manufactured Solutions and Experimental Results

Energies, 2018
To investigate turbulent reacting flows, a low-Mach number large-eddy simulation (LES) code called ‘LESsCoal’ has been developed in our group. This code employs the Germano dynamic sub-grid scale (SGS) model and the steady flamelet/progress variable ...

From Rainfall to Rumors: Interpreting the 2024 Bangladesh Floods Through Numbers, Narratives, and Information Gaps

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract When severe floods struck southeastern Bangladesh in August 2024, competing explanations emerged. Meteorological analysis revealed that extreme precipitation was exacerbated by the Madden‐Julian Oscillation and jet stream dynamics. However, alternative narratives proliferated on social media, particularly claims that India deliberately ...

Initiation of the detonation in the gravitationally confined detonation model of Type Ia supernovae

, 2009
We study the initiation of the detonation in the gravitationally confined detonation (GCD) model of Type Ia supernovae (SNe Ia). Initiation of the detonation occurs spontaneously in a region where the length scale of the temperature gradient extending ...

OH planar laser-induced fluorescence measurement for H2/O2 jet diffusion flames in rocket combustion condition up to 7.0 MPa

Journal of Thermal Science and Technology, 2019
This study focuses on the application of OH planar laser-induced fluorescence (OH-PLIF) in high-pressure rocket combustion conditions, up to 7.0 MPa. The signal to noise ratio of PLIF degrades in high-pressure combustion owing to effects such as line ...

Identifying Food Packaging Migrants: Current Analytical Capabilities, Challenges, and Future Prospects

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT The migration of intentionally and non‐intentionally added substances (IAS/NIAS) from food packaging into foodstuffs presents a significant challenge to consumer health and food safety. Accurate and comprehensive identification of these chemical migrants is therefore paramount.

Analysis of Interaction between Flame Torch and Independent Cocurrent Flow

Механика машин, механизмов и материалов, 2013
The paper presents a theoretical analysis of the flame spraying with an independent source of cocurrent flow. The spraying process is represented by "three-layer model", describing the motion of a two-phase jet in cocurrent flow.

Laboratory Experiments on Savannah and European Boreal Forest Fire Emissions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract Landscape fire is among the largest sources of aerosols and trace gases globally. However, the emissions are highly variable and strongly affected by the type of biomass and combustion characteristics. We investigated the effect of combustion characteristics on the burning emissions from three biomass types: woody plants and grasses from ...
