Experimental Investigation of Burning Liquids in Reduced Oxygen
Fire and Materials, EarlyView.ABSTRACT The effects of oxygen concentration on combustion of gases have been investigated on fundamental levels in several studies. However, the same type of fundamental studies has not been made for liquid or solid fuels due to complex relationships between flame structure and changing mass loss rates (MLR).
