We present a heat release dynamics model which utilizes a well-stirred reactor (WSR) model and one-step kinetics to describe the unsteady combustion process. The model incorporates the linearized mass and energy equations to describe the response of the reactor to external perturbations, and is cast in the form of a first order filter. The model is able to predict the phase between the mass flo...

In-situ combustion in porous media find applications in a variety of problems. Existing models to date are based on a continuum description, in which effective porous media are used. In this report, we consider the use of dual pore networks (pores and solid sites) for modeling the effect of the microstructure on combustion processes in porous media. The model accounts for flow and transport of ...

CFD analysis on the MSW incinerator combustion chamber provides crucial insight on the thermal flow fields, but a difficulty arise from the boundary conditions on the waste bed in which the combustion is governed by complicated heat and mass transfer phenomena. Solid waste bed combustion models are constructed to predict the combustion process and corresponding generation of gas phase species b...

In this study, a reputable Kalina cycle system, KCS 11, is simulated and analysed. Within this efficient cycle, there are three heat exchangers: the first heat exchanger is designated for heat absorption from the heat source, the second heat exchanger is designed for heat release to the cold source, and the third heat exchanger is designed for energy recovery. In order to achieve precise si...

Results show that the both t...

B combustion is a very large source of aerosol particles on a global scale. It is estimated that 20 % of the black carbon and 30 % of the organic carbon aerosol mass emissions are due to wild land fi res and intentional burning of agricultural waste in Asia. However in those numbers residential fuel combustion is not included, which is considered a larger source of black carbon and organic carb...
