Auto Ignition


Auto ignition in turbulent flows plays an important role in the field of Diesel engine combustion. Experimental investigations on a counterflow burner allow to better understand the interaction of chemical reaction and turbulence. In this particular flow geometry two turbulent jets, one of a fuel-nitrogen mixture and one of hot air, are arranged to directly oppose each other to form a free stagnation plane. The burner is equipped with a heating device which allows to increase the air temperature up to 1100°C until auto ignition occurs.


Applied measurement techniques:

  • PIV (Particle Image Velocimetry)
  • LIF (Laser Induced Fluorescence)
  • Rayleigh scattering
