Flamelet Characteristics of Gaseous and Spray Lifted Flames on Two-Dimensional Direct Numerical Simulations

open access: yesJournal of Fluid Science and Technology, 2008
The detailed behaviors of gaseous and spray lifted flames are studied by two- dimensional direct numerical simulations (DNS), and the characteristics of the flamelets are investigated in terms of two key variables for flamelet modeling, namely mixture ...

Numerical Simulation of Premixed Methane–Air Explosion in a Closed Tube with U-Type Obstacles

open access: yesEnergies, 2022
Given the spatial structures and functional requirements, there are a number of different types of obstacles in long and narrow confined spaces that will cause a premixed gas explosion to produce greater overpressure and influence the flame behavior for ...

Instability of lean H2-O2-CO2 premixed flames on a flat burner

open access: yesNihon Kikai Gakkai ronbunshu, 2015
Global warming and air pollution mainly caused by emissions of CO2 and NOx are serious problems. We focus on a lean H2-O2 premixed flame because H2-O2 premixed flame emits no CO2 and NOx.

Development of laminar burning velocity measurement system in premixed flames with hydrogen-content syngas or strong oxidizer conditions in a slot burner

open access: yesCase Studies in Thermal Engineering, 2022
This study presents the experimental determination of laminar burning velocity for critical premixed flames with multiple fuels or strong oxidizers. Experiments were conducted with a slot burner under methane/air, methane/nitrous oxide, and syngas (CH4 ...

Utilization of transport of species and heat release to a DRG-method-based reduction

open access: yesJournal of Thermal Science and Technology, 2018
We propose a new DRG-based mechanism reduction method that considers heat release rate (HRR), transport of species, and reaction rate. In the original DRG method developed by T. Lu and C. K.
