Quantum ignition of deflagration in theFe8molecular magnet

Deflagration with quantum and dipolar effects in a model of a molecular magnet

Plasma-assisted ignition and deflagration-to-detonation transition.

Non-equilibrium plasma demonstrates great potential to control ultra-lean, ultra-fast, low-temperature flames and to become an extremely promising technology for a wide range of applications, including aviation gas turbine engines, piston engines, RAMjets, SCRAMjets and detonation initiation for pulsed detonation engines. The analysis of discharge processes shows that the discharge energy can b...

prediction of ignition delay period in d.i diesel engines

a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...

LES study of deflagration to detonation mechanisms in a downsized spark ignition engine

Using 15 LES cycles of a high load / low speed spark ignition engine operating point, two different fresh gases autoignition regimes called knock and super-knock are analyzed. A direct “a posteriori” analysis of pressure waves and autoignition heat release observed in LES is proposed. It reveals that low to moderate knock intensity, corresponding to late spark timings (ST) is characterized by o...

Fusion Ignition Research Experiment (fire) Magnet System Structural Analyses

The toroidal field coil system of the FIRE tokamak utilizes inertially cooled, copper alloy Bitter plate type magnets which are LN2 cooled between shots. The baseline configuration is wedged. C17510 high strength, high conductivity beryllium copper alloy developed for BPX is proposed for the conductor. These design choices were made after considering a number of alternative structural concepts ...
