Noise, Vibration, and Harshness (NVH) Challenges in Hydrogen Internal Combustion Engine Vehicles

open access: yesEnergy Science &Engineering, Volume 14, Issue 2, Page 1067-1080, February 2026.
ABSTRACT This paper presents a state‐of‐the‐art literature review on noise, vibration, and harshness (NVH) in hydrogen‐fuelled internal combustion engines. Studies published between 2011 and 2025 were screened, covering fundamental flame physics, test‐bench work, and recent prototype vehicles.

Data-driven propagation prediction of subsonic and supersonic turbulent jets by combining self-similarity analysis model and artificial neural network

open access: yesApplications in Energy and Combustion Science
Previous self-similarity analysis models for turbulent jet flames (TJF) have inherent limitations in the flame tip location and velocity prediction based on experimental data.

A Causal Relationship Between Boron Seeds and the Selectivity and Growth Mode of Boron Nitride Nanotubes in Inductively‐Coupled Plasma

open access: yesSmall, Volume 22, Issue 9, 12 February 2026.
Boron seed formation governs BNNT selectivity in an inductively‐coupled plasma system. Local thermodynamics and flow conditions control the abundance and the size of these seeds. BNNT selectivity scales with seed abundance, while the nanotube diameters remain largely unaffected despite seed size changes.

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

open access: yesEnergies, 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 ...

Large Eddy Simulation of a Turbulent Nonpremixed Jet Flame Using a Finite-Rate Chemistry Model [PDF]

open access: yes, 2009
Large eddy simulation (LES) is conducted of a turbulent piloted nonpremixed methane jet flame. This flame has been studied experimentally at Sandia National Laboratories. The subgrid scale (SGS) closure in LES is based on the scalar filtered mass density

Reconstructing Environmental and Microbial Ecosystem Changes Across the Permian–Triassic Mass Extinction at Lusitaniadalen, Svalbard

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 2, February 2026.
Abstract The Permian–Triassic environmental crisis triggered fundamental changes in marine ecosystems, culminating in the most severe biodiversity crisis of the Phanerozoic. Yet, the environmental and geochemical conditions governing the crisis and ecosystem recovery remain debated.

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

open access: yesJournal 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 ...

Investigations of eddy coherence in jet flows [PDF]

open access: yes
In turbulent shear flow the term coherent structures refers to eddies which are both spatially coherent, i.e., large eddies, aand also temporally coherent, i.e., they retain their identities for times which are long compared with their time scales in ...
