Dear Author

there are more equations to test the flow inside combustion and you can check it if turbulence or laminar.

by experimental you can used high speed camera and then check it by using image processing

Combustion (homogeneous mixing or heterogeneous mixing) taking place will be turbulent in nature rather than laminar nor transient. If there is a means of determination, theoretically it will be calculated by Reynolds number and it depends on the type of combustion chamber (shape as plate, tubes or duct) in which combustion is taking place. Experimentally, the combustion phenomena or swirl occuring in a combustion chamber can be captured by cameras fitted inside and seeing on computer.

Isam Mejbel Abed,

Thank you for your reply but your answer is not clear to me. Even if I accept your remark, it needs to be more extended. Please tell me what equations could be used to know if the combustion is laminar or turbulent or transient ?

Image processing? then old scientists have used image processing to determine the regime of combustion, in the past?
