The influence of the flame’ shape to its heat flux

In the fire,the shape of the flame is unfixed,so specific geometries are used in the engineering calculations,which can simplify the calculations of the radiative transfer.The geometries always used are column flame,cone flame,cube flame,rectangle flame and point flame.The paper calculates the heat flux of the five shapes of the flame with the Monte Carlo method.Comparing the results gets the influence factors of the flame’ shapes to their radiation heat flux.
