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.
