Scaling Law for Marginal Ignition

LLE Review, Volume 87 153 Introduction In recent years, a considerable effort1–6 has been made to determine the minimum energy required for ignition in inertial confinement fusion (ICF) implosions. Though different conclusions have been reached by different authors, consensus is that the minimum energy required for ignition is a strong function of the shell implosion velocity as well as the she...

Improved Knock Detection Method Based on New Time-Frequency Analysis In Spark Ignition Turbocharged Engine

Premature combustion that affects outputs, thermal efficiencies and lifetimes of internal combustion engine is called “knock effect”. However knock signal detection based on acoustic sensor is a challenging task due to existing of noise in the same frequency spectrum. Experimental results revealed that vibration signals, generated from knock, has certain frequencies related to vibration resonan...

Photo-ignition of Carbon Nanotube for Ignition of Liquid Fuel Spray and Solid Fuel

We have studied the ignition of liquid fuel and certain solid fuels by the photoignition of single wall carbon nanotubes (SWCNTs). Our investigation includes the effect of solid additives such as aluminum nano-particles and solid oxidizers such as ammonium perchlorate (AP) on the photoignition characteristics. We have shown that by mixing CNT with other nanoparticles and powdered material, the ...
