Comparison of spray combustion for Jet-A and diesel in a constant volume chamber

open access: yes, 2013
This work investigates the effect of ambient conditions on jet-A spray combustion in an optical constant volume combustion chamber. Based on the data of jet-A and diesel fuel data obtained from previous experiments, a comparison between jet-A and diesel ...

Reaction-diffusion effects on species mixing rates in turbulent premixed methane-air combustion

open access: yes, 2009
The scalar mixing time scale, a key quantity in many turbulent combustion models, is investigated for reactive scalars in premixed combustion. Direct numerical simulations of threedimensional, turbulent Bunsen flames with reduced methane-air chemistry ...

Quantitative prediction of combustion modes, combustion intensity, and ignition delay times

open access: yes, 2019
The combustion modes, combustion intensity, and ignition delay times are quantitatively predicted by the newly-extended ignition criterion [1-3]. DME and ethanol are used to be representative of NTC and non-NTC fuels. The predictive accuracy is validated

Application of the first combustion model to spray combustion

open access: yesApplied Thermal Engineering, 2004
Liquid fuel is of interest to apply to gas turbines. The large advantage is that liquids are easily storable as compared to gaseous fuels. Disadvantage is that liquid fuel has to be sprayed, vaporized and mixed with air. Combustion occurs at some stage of mixing and ignition.
