Objective
Further development of a theory of high-voltage nanosecond pulse discharge in the form of fast ionization wave (FIW) and chemical reaction rates under nonequilibrium conditions; Experimental investigation of the ignition of fuel-air mixtures under independent variation of translational-rotational temperature of the gas and excitation of internal degrees of freedom with FIW and shock wave simultaneous action; Study of ignition and detonation development by action of the FIW and under the multi-point spark ignition; comparative analysis of FIW and spark ignition efficiency. Numerical model elaboration, which is able to describe general peculiarities of the ultra-fast FIW ignition of combustible mixtures and/or the multi-point spark ignition.
The research activities will be based on the close co-operation of scientists from the different teams. Experiments concerned combustible mixtures ignition under the FIW action will be performed in Moscow Institute of Physics and Technology, Russia. Experimental investigations of multi-spark ignition of combustible mixtures will be carried out in the Ben-Gurion University of Negev, Israel.
The numerical model of spark ignition and ignition under the high voltage FIW breakdown will be developed by teams from the University of Rouen, France, and Krzhizhanovsky Power Engineering Institute, Russia. The results of numerical simulation will be compared with experimental data received in the framework of the project.
The expected results are as follows:
- The determination of conditions for different regimes of reactions with strong interaction of vibrationally excited products and reagents.
- Experimental determination of conditions of the FIW development in various mixtures.
- Testing of homogeneity and simultaneity of combustion process in all regions of the discharge volume.
- Determination of the value of ignition threshold shift vs initial gas temperature, mixture composition and gas excitation degree in the FIW.
- Comparison of the two different techniques -- FIW and spark -- of mixture ignition.
- Numerical model elaboration, which is able to describe general peculiarities of the ultra-fast ignition of combustible mixtures under action of the fast ionization wave.
