Shock-tube combustion studies of atomized fuels in the reflected-shock region Conference Paper uri icon

abstract

  • A liquid-spray injection system has been implemented at the University of Central Florida Gas Dynamics Laboratory to study fundamental combustion phenomena including ignition delay time measurements, soot production, and activation energies of petroleum-based and synthetic hydrocarbon fuels. The current approach uses a finely atomized jet of fuel that is injected from the endwall of a shock tube. The micron-scale fuel droplets are heated and combusted behind the reflected shock wave at elevated temperatures. Repeatability and initial characterization of the electronically controlled, autonomous system has been performed using ignition delay time measurements of kerosene droplets over consistent temperature (1260 K) and pressure (1.4 atm) conditions behind the reflected shock. Details on the first phase of the design and implementation of the technique are provided along with ignition delay time measurements of kerosene at low pressures.
