Shock tube study on auto-ignition delay of kerosene aerosol and its cracked mixture

摘要：

　　An aerosol shock tube with piston setup attached to reflection end is developed for ignition delay studies of liquid fuels.Piezoelectric gauge and photomultiplier with filter are used respectively to detect pressure and OH emission signals.Autoignition delay is obtained for kerosene aerosol and its cracked mixture at different temperature and pressure,equivalence ratios.The results show good linearity of ignition delay with temperature inversion at different pressure and equivalence ratio.At high pressure,data of delay is close for aerosol and heating kerosene.But difference is obviously at low temperature.During burning,local shock waves are generated and propagate into burnt and unburnt mixture.
