英文摘要: Abstract(#br)The main objective of this work is to study the mean flame height and flame radiative heat flux of medium scale thermal buoyancy source with different aspect ratios in a sub-atmospheric pressure at high altitude, which has not been investigated before. Two series of radiative heat flux experiments of medium scale thermal buoyancy source were conducted separately in Hefei (altitude: 50m, pressure: 100kPa) and Lhasa (altitude: 3650m, pressure: 64kPa). The mean flame heights of rectangular heat sources burners were obtained by image processing method and the radiation flux was measured by a water cooled wide angle radiometer. Four medium scale rectangular thermal source burners with same surface area...
