Flame height

n. The vertical dimension from the ground to the tip of the flame.  


  • Discussion


When the flame is burning up or down a slope, flame height is defined as the vertical distance from the base of the leading edge of the flame to the flame tip. On a slope flame height can be calculated from measurements of flame angle, slope steepness and flame length.


See Anderson and others (2006) for further discussion.


  • Units


    Preferred units for flame height are m in technical reports and papers. Fire Management in the United States still uses the English units ft. See the following flame height units conversion table for conversion factors.
