Characterization And Evaluation Of Cordless Nailer Performance For Liquid And Gaseous Fuels, Mark Carioscio
Characterization And Evaluation Of Cordless Nailer Performance For Liquid And Gaseous Fuels, Mark Carioscio
Master's Theses (2009 -)
The Paslode Cordless XP Framing Nailer is a combustion-powered nail gun that operates using a fuel blend of a propylene and 1-butene. This tool is designed to drive nails using a piston driven by a combustion reaction. The current fuel blend is able to fire approximately 1200 shots per fuel cartridge and match the energy output of pneumatic, corded nailers on the market. This thesis is written with the intent to gain a better understanding of the operation of the tool and how its performance varies when the fuel source is altered. A bizonal combustion model was created to simulate …

Understanding the interaction between transport, reaction and morphology at the scale of individual char particles is important for optimizing solid fuel gasification and combustion processes. However, most particle-scale models treat porous char particles as an effective porous continuum, even though the presence of large, irregular macropores, voids and fractures render such upscaled treatments mathematically invalid, and the models non-predictive. A new modeling framework is therefore proposed to elucidate the impact of morphology on char particle gasification and combustion. A pore-resolving, transient, three-dimensional simulation for gasification of a realistic coal char particle is developed based on X-ray micro-computed tomography (micro-CT). The …
