Experimental and Numerical Investigation of Laminar Burning Velocities of Artificial Biogas Under Various Pressure and CO2 Concentration [PDF]

E3S Web of Conferences, 2019
As a renewable and sustainable fuel made from digestion facility, biogas is composed predominantly of methane (CH4) and carbon dioxide (CO2). CO2 in biogas strongly affects its combustion characteristics.

The influence of turbulence on the structure and propagation of enclosed flames [PDF]

, 1966
Although it has long been established that burning rates can be appreciably increased by turbulence, the actual extent of this increase and the precise mechanism involved are still far from clear.

Flame Enhancement and Quenching in Fluid Flows [PDF]

, 2002
We perform direct numerical simulations (DNS) of an advected scalar field which diffuses and reacts according to a nonlinear reaction law. The objective is to study how the bulk burning rate of the reaction is affected by an imposed flow.

Safety of Sodium‐Ion Batteries: Evaluation and Perspective from Component Materials to Cells, Modules, and Packs

Advanced Energy Materials, EarlyView.
This review provides a bottom‐up evaluation of sodium‐ion battery safety, linking material degradation mechanisms, cell engineering parameters, and module/pack assembly. It emphasizes that understanding intrinsic material stability and establishing coordinated engineering control across hierarchical levels are vital for preventing degradation coupling ...

Turbulent burning velocity in combustion chamber of SI engine fueled with compressed biogas

Vietnam Journal of Mechanics, 2015
Turbulent burning velocity is the most important parameter in analyzing pre-mixed combustion simulation of spark ignition engines. It depends on the laminar burning velocity and turbulence intensity in the combustion chamber.

Turbulent flame propagation and combustion in spark ignition engines [PDF]

, 1983
Pressure measurements synchronized with high-speed motion picture records of flame propagation have been made in a transparent piston engine. The data show that the initial expansion speed of the flame front is close to that of a laminar flame.

Composition‐Aware Cross‐Sectional Integration for Spatial Transcriptomics

Advanced Intelligent Discovery, EarlyView.
Multi‐section spatial transcriptomics demands coherent cell‐type deconvolution, domain detection, and batch correction, yet existing pipelines treat these tasks separately. FUSION unifies them within a composition‐aware latent framework, modeling reads as cell‐type–specific topics and clustering in embedding space.

IMPACT OF THE NOZZLE ANGLE, DISTANCE BETWEEN BURNERS, AND N2 ON BURNING VELOCITY OF THE DIFFUSOIN COUNTER FLAMES

Journal of Engineering and Sustainable Development, 2020
The achievement of precise measurements on the laminar diffusion flames plays a big role in the process of realizing a wide flames range. Despite most of fuel is likely burnt in the turbulent combustion, there is still data requirement for the data on ...
