Abstract

Small crystalline boron particles (1-15 (μm) in a pure oxygen atmosphere are ignited at the endwall of a high pressure (8.5 atm) shock tube to study the effect of particle size on ignition delay time. An infrared detector is used to observe B2B3 oxide layer removal from the boron particles, while a visible wavelength photodiode is used simultaneously to observe BO2 emission. Both infrared and visible data are presented showing particle size and temperature effects. Results compare favorably to theoretical predictions from a recent model.
