Combustion behavior of rotary solid porous burners (RSPB)

Two-dimensional Numerical Simulation of Combustion and Heat Transfer in Porous Burners

this study, combustion in a 5kW porous burner is simulated. The two dimensional Navier-Stokes, the energy and the chemical species transport equations are solved and a multistep kinetics mechanism (5 reactions and 7 species) is employed. Finite volume method is used for simulation. Thermal nonequilibrium is accounted for gas and solid temperature and radiation heat transfer is considered for so...

investigation on improvement of radial porous burners in comparison to conventional porous burners

in studies done on porous burner, generally burners with axial flow are considered. in this paper, porous burners with radial and axial flow have been modeled numerically and results of radial and axial porous burners with equal fuel consumptions are compared. the mechanism used in combustion phenomenon is 15 stage mechanisms which predict the pollutions production precisely. the results show a...

Complex dynamic behavior during transition in a solid combustion model

Through examples in a free-boundary model of solid combustion, this study concerns nonlinear transition behavior of small disturbances of front propagation and temperature as they evolve in time. This includes complex dynamics of period doubling, and quadrupling, and it eventually leads to chaotic oscillations. Within this complex dynamic domain we also observe a period six-folding. Both asympt...

Accommodative Behavior of Non-porous Molecular crystal at Solid-Gas and Solid-Liquid Interface

Molecular crystals demonstrate drastically different behavior in solid and liquid state, mainly due to their difference in structural frameworks. Therefore, designing of unique structured molecular compound which can work at both these interfaces has been a challenge. Here, we present remarkable 'molecular' property by non-porous molecular solid crystal, dinuclear copper complex (C6H5CH(X)NH2)2...
