Frontiers in Energy 2022, Volume 16, Issue 6,   Pages 1017-1026 doi: 10.1007/s11708-020-0716-x

Abstract: The interaction of multiple fires may lead to a higher flame height and more intense radiation flux thana single fire, which increases the possibility of flame spread and risks to the surroundings.For non-merging flames ( / >0.368), the flame height is almost identical to a single fire; for merging), a quantitative analysis of the flame height, merging point height, and air entrainment was formed,and the calculated merging flame heights show a good agreement with the measured experimental values
