We recently developed two different optical techniques in order to simultaneously measure transient two-dimensional profiles of velocity, temperature, and fuel concentration that were generated by a spreading flame over liquid fuels. One technique employs a particle-track system combined with a laser-sheet system (LSPT) and a high-speed camera, while the other technique employs dual wavelength holographic interferometry (DWHI). The LSPT system revealed transient two dimensional profiles of flame-induced flow, while DWHI revealed two-dimensional profiles of fuel concentration over liquids. In this paper we present a series of velocity profiles for a pulsating flame spread over 1-propanol and concentration profiles for gaseous 1-propanol determined with LSPT and DWHI, respectively.
