Abstract


A new method for instantaneous measurement of temperature, size and velocity of micro-droplets has been developed.The method is based on the well-known 2-color laser-induced fluorescence (2cLIF) technique, but usesa pulsed laser for 2-dimensional imaging without motion blur and an adjusted dye mixture for suppression of LIFMDRsby utilizing the MDR-enhanced energy transfer effect. This work presents the development steps that arenecessary to verify feasibility of pulsed 2D-2cLIF-EET for micro droplet and hollow-cone spray applications.
