Effect of silane addition on acetylene ignition behind reflected shock waves

Ignition delay time and species profile measurements are reported for the combustion of C 2H 2/O 2/Ar mixtures with and without the addition of silane for temperatures between 1040 and 2320 K and pressures near 1 atm. Characteristic times, namely ignition time and time to peak, were determined from...

Description
Summary:Ignition delay time and species profile measurements are reported for the combustion of C 2H 2/O 2/Ar mixtures with and without the addition of silane for temperatures between 1040 and 2320 K and pressures near 1 atm. Characteristic times, namely ignition time and time to peak, were determined from the time histories of CH* (A 2Δ → X 2Π) and OH* (A 2Σ + → X 2Π) emission near 430 and 307 nm, respectively. For the cases without silane, there is good agreement between the present data and some recent acetylene oxidation results. Small SiH 4 additions (
