Direct determination of burning velocity during aluminium flame propagation

Chemical Engineering Transactions, 2022
Numerical simulations are needed to model accurately the consequences of dust explosions. One key parameter for modelling the flame propagation is the burning velocity (ie the consumption rate of the reactants by the flame front).

Simultaneous measurement of burning velocity and turbulence intensity ahead the flame front during aluminum flame propagation

Chemical Engineering Transactions, 2022
Numerical simulations of the flame propagation process are mandatory to predict the consequences of dust explosions. One key parameter of these models is the burning velocity, i.e. the consumption rate of the reactants by the flame front.

Laminar burning velocity of gases vented from failed Li-ion batteries

, 2021
In the last decade, several fires and explosions caused by Li-ion batteries (LIBs) have been reported. This can be attributed to the thermal runaway and catastrophic failures of LIBs that release combustible gases, which when mixed with air can lead to ...

Laminar burning velocity measurements of ethanol+air and methanol+air flames at atmospheric and elevated pressures using a new Heat Flux setup

Combustion and Flame, 2021
A new setup for burning velocity measurements of liquid fuels at elevated pressures using the Heat Flux method has been constructed. The burner design has been improved comparing to previous studies in this and other laboratories.

Experimental study and kinetic analysis of the laminar burning velocity of NH3/syngas/air, NH3/CO/air and NH3/H2/air premixed flames at elevated pressures

Combustion and Flame, 2020
Mixing ammonia with syngas can be a promising way to overcome the low reactivity of ammonia, allowing it to find usage in IGCC (Integrated Gasification Combined Cycle) systems and gas turbines for power generation.

Flow field and local burning velocity affected by stretch in swirl flow of turbulent premixed flames

Journal of Thermal Science and Technology, 2022
In this study, we have investigated turbulent premixed flames affected by local stretch in a swirl flow, measured by the simultaneous OH-PLIF/SPIV system. Evaluating the transient of burning velocity and stretch rate, the flow and the flame dynamics in a
