Streamer Discharge Modeling for Plasma-Assisted Combustion

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

Streamer simulations are properly described. Streamer simulation results looks good to expect  that the streamer part of the model to be valid . I am sorry for not providing feedback on combustion part.

The main comment for this manuscript is that first paragraph of the results section should be  split and moved into the relevant parts of section 2 (for initial values lines 154, 157, and geometry anywhere before 141). 

Minor comments:

1. equation 3, remnant space charge is relevant even for negative ions so S should be added even there.
2. reference 39 on line 170 is not proper
3. reference 43 on line 200 is not proper
4. In section references please double check them. e.g. reference 26 is written badly.

Reviewer 2 Report

Comments and Suggestions for Authors

The work is devoted to modeling of streamer discharge for plasma combustion of fuel-air mixture.

The work is topical. The introduction presents in sufficient detail a picture of the current state of research in this direction, which will be useful for readers. The work is of interest to specialists in the physics of low-temperature plasma, high-pressure gas discharge, and cold plasma generation. The results obtained are interesting, so the obtained results will be in demand.

The results are physically justified and do not cause doubts.

Comments and questions:

It is known that any result can be obtained in modeling. It all depends on what data, what chemical reactions, what reaction constants and what accuracy of these constants are put into the model. Therefore, authors should carefully justify all the input data used.

Is it possible to control the combustion processes (temperature, efficiency) by changing the geometry of the discharge gap, voltage amplitude, pulse repetition rate. Can the authors explain what the voltage rise rate is in their calculations? What would change if they changed the voltage rise rate? The processes of streamer generation, filament generation, appearance of excited particles, etc. depend very strongly on the rise rate of voltage on the discharge gap.
