Numerical Simulation of Combustion with Porous Medium in I.C. Engine
Porous media has interesting features in compared with free flame combustion due to the extended of the lean flammability limits and lower emissions. Advanced new generation of internal combustion (IC) engines are expected to have far better emissions levels both gaseous and particulate matter, at the same time having far lower fuel consumption on a wide range of operating condition. These c...
متن کاملCombustion Fronts in a Porous Medium with Two Layers
We study a model for the lateral propagation of a combustion front through a porous medium with two parallel layers having different properties. The reaction involves oxygen and a solid fuel. In each layer, the model consists of a nonlinear reaction–diffusion–convection system, derived from balance equations and Darcy’s law. Under an incompressibility assumption, we obtain a simple model whose ...

متن کاملPhase Changes in Boron Ignition and Combustion
The ignition of electrically heated boron filaments in air and argon/oxygen mixtures has been studied. Boron filament resistance, temperature, and emissions from the BO and BO2 bands were monitored. Preliminary experimental data have also been obtained to characterize the phases formed inside burning boron particles produced and ignited from the same filament material by feeding a vibrating bor...
متن کاملOxygen-flask combustion with light beam ignition.
A robust oxygen-flask combustion system was developed using light beam ignition. An appropriate amount of environmental sample was wrapped with a small piece of filter paper and held in a basket made of platinum-zirconium spiral. After the sample was inserted into an oxygen-filled flask containing an acid mixture, the light beam from an overhead projector lamp was focused to ignite the sample. ...
