intermetallic phase formation and oxidation reaction during combustion synthesis (cs) of ni-ti equiatomic mixture are affected by mechanical activation (ma) and pre-heating conditions. important parameters are ignition time, reaction duration, temperature rise, microstructural change, titanium oxidation and intermetallic phase formation. superelasticity and shape memory effects are influenced b...

Flame radiation is one of the important causes wildland–urban interface (WUI) fires. PMMA, pine needle and wood are most common fuels in WUI fires, but radiant distance effect on flaming ignitions as well subsequent burning behavior still poorly understood. This work represents an experiment to investigate autoignition pine-needle pine-wood fuel beds with different distances (25 mm–100 mm) unde...

The ignition of a gaseous reactive mixture subject to a localized energy source is analysed using large activation energy asymptotics. The energy released by the source results in a thermal non-uniformity in a small region of the gas. We distinguish two different regimes, non-diffusive and diffusive, depending on the dominant cooling mechanism during the ignition stage: expansion effects or hea...

In this work, an experimental study investigating dielectric barrier discharge (DBD) plasma-assisted ignition in methane-air flows at near-atmospheric pressure is presented. Discharges are produced using 10 ns duration high voltage pulses maximum 3 kHz pulse repetition rate. The goal to check the feasibility of plasma as source for ignition-stabilized combustion a wide range equivalence ratio, ...
