Ignition delay time correlations for distillate fuels
Fuel, 2017 Abstract Ignition delay times were measured behind reflected shock waves in a shock tube for a wide variety of distillate fuels over a range of temperatures, pressures and mixtures. The fuels studied include: jet fuels (JP-5, JP-8, and Jet A), rocket propellants (RP-2), diesel fuels (F-76 and DF-2) and gasoline.

Direct sensitivity analysis for ignition delay times
Combustion and Flame, 2019 Abstract The sensitivity coefficients of ignition delay time with respect to chemical kinetic rate parameters is traditionally calculated using a brute force approach wherein the number of initial value problems solved is no fewer than the number of rate parameters. By reformulating the underlying initial value problem as a boundary value problem, it
