A new analytical study performed to investigate the effect of the temperature difference between gas and particle in propagation of the spherical flames. The combustible system is containing uniformly distributed volatile fuel particles in an oxidizing gas (Air) mixture. The model includes evaporation of volatile matter of dust particles to known gaseous fuel (methane) and the single-stage reac...

Protective coatings that resist oxide scale growth and decrease chromium evaporation are necessary to makestainless steel interconnect materials for long-term durable operation of solid oxide fuel cells (SOFCs). Inthis study a layer of manganese was coated on the surface of AISI 441 ferritic stainless steel which is used insolid oxide fuel cells for interconnect applications. The oxidation beha...

We study the effects of a liquid lithium curtain used as the first wall for the engineering outline design of the Fusion Experimental Breeder (FEB-E). Relationships were obtained between the surface temperature of a liquid lithium curtain and the effective plasma charge, fuel dilution, and fusion power production. Results indicate that, under normal operation, the evaporation of liquid lithium ...

A numerical model is developed to predict the aqueous concentrations of sparingly soluble compounds resulting from oil, fuel, or chemical spills onto rivers. The model computes the concentration of compounds both in the slick phase and in the aqueous phase by simulating the processes that affect the fate of the spilled compound. Processes simulated by the model include spreading and drifting of...

A fuel injection system in a diesel engine has different processes that affect the complete burning of combustion chamber. These include primary and secondary breakups liquid droplets evaporation. In present paper, evaporation two fuels been modelled numerically. Evaporation n-heptane n-decane is governed by conservation equations mass, energy, momentum, species transport. Results have plotted ...

A new algorithm for the auto-selection of quasi-components and components (QC/Cs) in ‘multi-dimensional quasi-discrete’ model is suggested. This applied to analysis heating evaporation multi-component fuel droplets. It allows one automatically select QC/Cs update initial selection during droplet evaporation. The expected be applicable a wide range fuels blends. can directly implemented into CFD...

The present study is concerned with measuring and simulating soot formation and combustion in turbulent liquid fuel spray flames. Soot concentrations inside the combustor are measured by filter paper technique. The simulation is based on the solution of the fully-coupled conservation equations for turbulent flow, chemical species kinetic modeling, fuel droplet evaporation and combustion and...
