An experimental investigation of iso-octane ignition phenomena
High-speed digital imaging has been used in rapid compression facility (RCF) studies to investigate ignition phenomena of iso-octane/air mixtures. Sequential images were captured for each experiment. The results indicate the existence of two ignition regimes. In one domain, ignition is rapid, typically less than 76 μs, and ignition occurs simultaneously throughout the test volume. In the other ...
متن کاملIgnition Phenomena and Controlled Firing of Reaction-bonded Aluminum Oxide
The reaction-bonded aluminum oxide (RBAO) process utilizes the oxidation of attrition-milled Al/Al2O3/ZrO2 powder compacts, that are heat treated in air, to make alumina-based ceramics. A simultaneous mass and energy balance has been used to model the propagation of the ignition front that has been observed during reaction-bonding. The model is used to determine conditions under which ignition ...
متن کاملLaser Plasma-initiated Ignition of Engines
Laser ignition is considered to be one of the most promising future ignition concepts for internal combustion engines. It combines the legally required reduction of pollutant emissions and higher engine efficiencies. The igniting plasma is generated by a focussed pulsed laser beam. Having pulse durations of a few nanoseconds, the pulse energy Ep for reliable ignition amounts to the order of 10 ...
متن کاملIF/P7-25 Studies of Phenomena Related to Fast Ignition of a Fusion Target by Laser-Driven Proton Beams
Generation of high-current proton beams of parameters scalable to those required for fast ignition of a fusion target was studied numerically and experimentally. Using a hydrodynamic relativistic 2D code, it was found that laser-induced skin-layer ponderomotive acceleration (SLPA) makes possible to produce collimated proton beams of MA currents and TA/cm current densities at relativistic laser ...
متن کاملcontrol of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
