A Study on Modeling of Turbulent Burning Velocity Based on Local Burning Velocity for Hydrogen Mixtures

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 2008
This study is made to attempt to establish a prediction model of tubulent burning velocity for hydrogen mixtures based on the local burning velocity of turbulent flames instead of laminar burning velocity. The turbulent burning velocity characteristics of the specific mixtures having the same laminar burning velocity SL0 with different equivalence ...

Modeling pressure effects on the turbulent burning velocity for lean hydrogen/air premixed combustion [PDF]

open access: yesProceedings of the Combustion Institute, 2019
We investigate and model pressure effects on the turbulent burning velocity over a wide range of pressures and turbulence intensities with the direct numerical simulation (DNS) of statistically planar turbulent premixed flames for lean hydrogen/air ...

Laminar burning velocity predictions for C1 and C2 hydrofluorocarbon refrigerants with air

open access: yes, 2020
Due to their high global warming potentials, many existing working fluids are being phased out. Their replacements will often be slightly flammable, and the burning velocity of refrigerant-air mixtures is a metric for ranking their flammability. To allow

Cracking the Code: Which Ocular Symptoms Predict Dry Eye Signs? Insights From a Large International Sicca Registry

open access: yesArthritis Care &Research, EarlyView.
Objective The study aimed to identify symptom‐based predictors of dry eye disease (DED) signs in the Sjögren's International Collaborative Clinical Alliance (SICCA) cohort. Methods We performed a retrospective analysis examining 16 ocular symptoms (most graded 0–4) and artificial tear (AT) use (graded 0–3) as predictors of DED signs (abnormal ocular ...

Turbulent and Stable/Unstable Laminar Burning Velocity Measurements from Outwardly Propagating Spherical Hydrogen-Air Flames at Elevated Pressures

open access: yesJournal of Thermal Science and Technology, 2006
The laminar burning velocity of pre-mixed hydrogen-air mixtures was measured in a fan stirred combustion bomb. Unstretched laminar burning velocities and Markstein lengths were obtained at 0.10MPa for equivalence ratios of 0.4, 0.6, 0.8 and 1.0 using ...

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

open access: yesJournal 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 ...
