Gasoline Confined In Nano-Porous Media, Matthew Giso
Honors Theses
The heat of combustion was determined for gasoline confined in nano-porous media of differing pore size by bomb calorimetry. The heat of combustion of the confined fuels was comparable to that of bulk within the experimental uncertainty. This suggests that all of the confined fuel burns without any flame quenching and no chemical interactions at the interface between pore walls and fuel mitigate combustion.

Combustion instability is characterized by periodic fluctuations during the combustion process. Such instabilities can cause a reduction in engine performance and damage to engine components. In liquid fueled combustion, some types of combustion instability may be driven by changes in fuel droplet size distribution. The fuel droplet size distribution can be changed if the original or “primary” fuel droplets are broken apart by the flow. This is called secondary droplet breakup. The smaller drops that are created during breakup are consumed more rapidly and increase the energy release rate, which may act as a sustaining force of the instability. Currently, …
