The objective of NEXTFLAME is to progress in the understanding and modelling of the spray flame phenomena by building and sharing databases of experimental and numerical data with their comparisons and analysis. Compared to existing studies where the flow complexity often limits the experimental diagnostics and the comparison with numerical simulation, we want to deal with controlled (laminar) configurations that will still be capable to mimic the fundamental physics of spray combustion encountered in more complex (turbulent) flow cases such as real combustors.
Experimental study
The experimental setup is a laminar two-phase counterflow burner equipped with a pulsated air-flow controller.
Numerical study with academic codes
1D and 2D numerical codes developed at EM2C and CORIA are used to investigate the steady and transient regimes.
Numerical study with a semi-industrial code
3D two-phase flow computations of the experimental configuration are performed using the AVBP code of CERFACS.
