Pollutant emissions from combustion systems are a major area of concern with today’s energy needs. Numerical simulations have helped with the design of clean and efficient combustion strategies over the years. However, with the emergence of new fuels and combustion modes, it is necessary to improve the computational models. In this research, improved NOx and soot models are developed which uses...

The blue-emitting phosphor cerium activated yttrium silicate, (Y1 mCem)2SiO5, was prepared via a novel synthesis technique called combustion synthesis. Combustion synthesis involves a highly exothermic redox reaction between metal nitrates and an organic fuel to produce a solid powder. The combustion synthesis parameter, the fuel-to-oxidizer ratio, has a direct effect on the physical properties...

Nickel titanium (NiTi) foams were made by combustion synthesis of powders with the help of ZrH2 as foaming agent and TiB2 as endothermic agent. In this paper, we investigated the effect of elemental powder size on the foaming. The powder size of Ni and Ti affected the ignition temperature of the combustion reaction, cell morphology and microstructure of the foams. The cell morphology of the foa...

The Cluster of Excellence (CoE) ̈Tailor-Made Fuels from Biomass ̈ (TMFB) takes an interdisciplinary research approach towards new synthetic fuels based on biomass feedstock. New target-designed synthesis pathways, employing novel catalytic systems, reaction solvents and tightly integrated production processes, which embed intensified process units for fuel production, are considered to create new...

nanocrystalline alumina powder has been synthesized using solution combustion method. the obtained nanocrystalline alumina powder was used as an efficient catalyst for the synthesis of imidazo[1,2-a]azine derivatives from one-pot three component reaction of benzaldehyde, 2-aminoazine and trimethylsilylcyanide under ultrasonic irradiation and refluxing condition. reusability of catalyst and shor...

The use of microwave heating to initiate combustion synthesis has been increasingly investigated in recent years because of its advantages over traditional methods. A simple mathematical model is used to model these experiments. The microwave power absorption term is modelled as the product of an Arrhenius reaction term with a function that decays exponentially with distance. The former represe...

combustion synthesis has been used to produce fe-(ti,w)c composites. a simple reactor was designed which made it possible to ignite the samples under controlled atmosphere. samples with different w/ti ratio were ingnited under argon atmosphere by an electric arc and a self-propagating reaction was initiated in each sample. different composites such as wc in fe-ti matrix, wc+(ti,w)c in fe matrix...
