Title

New Shock-Tube Facility For Studies In Chemical Kinetics At Engine Conditions

Abstract

A new shock-tube facility targeting lower temperature and long test times is described. The singlepulse shock tube uses either lexan diaphragms or die-scored aluminum disks of up to 4 mm in thickness. The modular design of the tube allows for optimum operation over a large range of thermodynamic conditions from 1 to 100 atm and between 600-4000 K behind the reflected shock wave. Test times up to 20 ms can be obtained using the proper driver-driven configuration featuring a longer driver section. The system includes a 'smart' gas handling and vacuum system; high temporal and special resolution, multi-channel data acquisition boards; and the capability to apply several optical diagnostics. The new facility allows for ignition delay time, chemical kinetics, high-temperature spectroscopy, vaporization, atomization, and solid particulate experiments. Details on the layout are presented, and the largest potential contributors to the overall uncertainty are identified.
