Measurements of ignition delay time on unsteady hydrogen jets.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1984
The paper describes an experimental study on the ignition of unsteady hydrogen jets injected into compressed high temperature air in the test section of a free piston shock tube. Pressure measurements as wall as the detection of light emission due to combustion of a hydrogen-oxygen gas mixture were made. We found that the compression process of the air

Bayesian Optimization Guiding the Experimental Mapping of the Pareto Front of Mechanical and Flame‐Retardant Properties in Polyamide Nanocomposites

Advanced Intelligent Discovery, EarlyView.
Bayesian optimization enabled the design of PA56 system with just 8 wt% additives, achieving limiting oxygen index 30.5%, tensile strength 80.9 MPa, and UL‐94 V‐0 rating. Without prior knowledge, the algorithm uncovered synergistic effects between aluminum diethyl‐phosphinate and nanoclay.

Scaling relation for high-temperature biodiesel surrogate ignition delay times [PDF]

Fuel, 2016
High-temperature Arrhenius ignition delay time correlations are useful for revealing the underlying parameter dependencies of combustion models, for simplifying and optimizing combustion mechanisms for use in engine simulations, for scaling experimental data to new conditions for comparison purposes, and for guiding in experimental design.
