Nanomaterials are attracted a great deal of attention from scientific community due to its unique properties and applications. The small size ferrites have opened the door for intensive research to utilize their properties for biomedical applications. Cobalt ferrite nanomaterials and its silver doped (Ag-doped) nanocomposites have been prepared using solid state combustion method. This combusti...

BACKGROUND Biomass and municipal solid waste offer sustainable sources of energy; for example to meet heat and electricity demand in the form of combined cooling, heat and power. Combustion of biomass has a lesser impact than solid fossil fuels (e.g. coal) upon gas pollutant emissions, whilst energy recovery from municipal solid waste is a beneficial component of an integrated, sustainable wast...

ZnFe2O4 mixed spinel ferrite nanoparticles obtained through a citrate-nitrate combustion method. Ignited products calcined at different temperatures in 600-900ºC range and effect of calcination treatment temperature investigated. Final Products characterized by X-ray Diffraction (XRD), Fourier-Transform Infrared spectroscopy (FTIR), and Field Emission Scanning Electron Microscopy (FESEM). The a...

Subject analysis of the potential of spontaneous combustion in coal layers with analytical and numerical methods has been always considered as a difficult task because of the complexity of the coal behavior and the number of factors influencing it. Empirical methods, due to accounting for certain and specific factors, have not accuracy and efficiency for all positions. The Rock Engineering Syst...

Computational fluid dynamics simulation of methane combustion using chemical kinetics is studied. Linear least squares data fit to measured concentrations and temperatures is used to modify reaction rate parameters in the Arrhenius rate equation for combustion of methane. The modification of reaction rate parameters influences the result of CFD-simulations to predict combustion at experimental ...

Two mechanisms control combustion noise generation as shown by Marble and Candel [1]: direct noise, in which acoustic waves propagate through the turbine stages and indirect noise, in which vorticity and/or entropy waves generate noise as they are convected through turbine stages. A method to calculate combustion-generated noise has been implemented in a tool called CHORUS. The method uses the ...
