Turbulent flame development in a high-pressure combustion vessel [PDF]
, 2005 The objective of this work was to extend the range of turbulent burning velocities presented in the literature by performing new measurements at elevated pressures over a range of turbulent velocities, u' (r. m. s. deviation from the mean velocity).

Burning velocity and the influence of flame stretch [PDF]
, 1991 A new technique is presented for determining burning velocities and stretch effects in laminar flames, and applied to a range of fuel/air mixtures. The speeds of expanding spherical flames, measured by high-speed schlieren cine-photography, are shown to

Hydrogen-Bond Enabled Phosphite Based Intrinsic Flame-Retardant Solid-Solid Phase Change Materials Using Catalyst/Solvent-Free Multi-Component Reaction for Battery Thermal Management. [PDF]
Adv Sci (Weinh)The phosphite group endows intrinsic flame retardancy, while the P = O bond enhances intermolecular interactions to realize solid‐solid phase transition. Battery thermal management tests show the materials extend the safe working time of lithium‐ion batteries by 200%. Cone calorimeter tests indicate a 14s delay in ignition time, and reductions of 37.6%,
