Counterflow Diffusion Flame

Abstract Ammonia, as a carbon-neutral fuel, draws people attentions recently. NH3/CH4 blends is considered as a kind of fuel. A numerical simulation of the effects of CO2 dilution on the combustion characteristics and NO emission of NH3/CH4 counterflow diffusion flame was conducted in this study. Diffusion flame structure, the influence of CO2 radiation characteristics on temperature and NO emission characteristics were studies at normal temperature and pressure. The dilution and radiation of CO2 reduce the flame temperature significantly. NO concentration decreased with the CO2 mole fraction increase effectively. The study extends the basic combustion characteristics of NH3 containing fuel.

Counterflow Diffusion Flame

This paper reports numerical investigation concerning the interaction of a laminar methane–air counterflow diffusion flame with monodisperse and polydisperse water spray. Commercial code ansys fluent with reduced chemistry has been used for investigation. Effects of strain rate, Sauter mean diameter (SMD), and droplet size distribution on the temperature along stagnation streamline have been studied. Flame extinction using polydisperse water spray has also been explored. Comparison of monodisperse and polydisperse droplet distribution on flame properties reveals suitability of polydisperse spray in flame temperature reduction beyond a particular SMD. This study also provides a numerical framework to study flame–spray interaction and extinction.

Due to the constant modernization of weapons and ammunition production, it has become necessary to search for new types of equipment. Within the research, we examine the possibility of using fluoroplastic as a reaction material which can replace explosives in ammunition used to destroy lightly armored and soft targets. The paper shows the results of experiments and mathematical simulation of the fluoroplastic striker penetrating into the light alloy barriers. The counterflow diffusion flame method was used to take into account the additional energy released as a result of interaction during the simulation
