| Abstract: | The supercritical fluid concept and progress of experimental study on evaporation and combustion of a fuel drop suspended in the supercritical environment are described in this paper.The piston driver which could compress gas to arrive a homogeneous high pressure and high temperature is introduced to study the fuel drop behavior in sub- and supercritical environment.The principle of the piston driver and final state estimation of the compressed gas are discussed.Cinematography, shadowgraph and planar laser induced fluorescence（PLIF） are briefly introduced for flow-field visualization and OH-PLIF imaging.Tunable diode laser absorption system（TDLAS） was utilized for temperature measurement.In contrast to drop imaging,the technologies of pressure and temperature measurements are adopted to identify the sub-,trans- and supercritical environment.The shortcomings of piston driver are also discussed. |
