“…They further proposed a dimensional scaling theory with the expression X r ∼ P 0.3−0.175α D 0.15 . The research findings of Zhao et al [88] also indicated an exponential decrease in flame radiation fraction with increasing pool diameter. Additionally, they found that with the decrease in environmental pressure, the flame height of n-heptane pool fires increased, and the burning rate decreased.…”

This paper presents a summary of and introduction to research on high-altitude and subatmospheric combustion concerning turbine and scramjet engines. The investigation includes theoretical analysis, experimental studies, and numerical simulations. The analysis encompasses the flow field structure, fuel atomization, and combustion performance. Subsequently, recent research on the combustion performance of liquid fuels, solid fuels, and gaseous fuels under high-altitude and low-pressure plateau environments is reviewed. This includes an evaluation of flame height, flame temperature, combustion rate, fire spread rate, and heat radiation flux. Additionally, combustion performance prediction models for high-altitude environments based on experimental and theoretical analysis have been introduced. Lastly, issues in subatmospheric combustion in the aerospace and plateau fire fields are presented based on the current research.
