Abstract

The Missouri S&T Thermodenuder was redesigned to analyze hybrid soot particles with volatile coatings by heating, then cooling an aerosol stream; this allows for measuring the change in size of the denuded particles. The original design carried with it practical limitations and it was found that the device had a less than satisfactory ability to allow particulates to penetrate through the sampling line. Through a combined thermodynamic interpretation of the design along with the use of the Aerosol Calculator Program, ideal design parameters were found to maximize the penetration of particles through the apparatus while maintaining its ability to drive off the volatile fraction on hybrid particles. These parameters were implemented in a new design which is to be tested for penetration and its denuding ability.

Biography

Graduating from Rolla High School in 2010, Valentine Hollingsworth has a strong interest in flow processes, particularly those associated with manufacturing. In pursuit this interest, he studies Chemical Engineering at Missouri University of Science and Technology. When not studying, he works with the Missouri S&T Center of Excellence for Aerospace Particulate Emissions Reduction Research to apply concepts adapted from chemical engineering courses to ongoing research in aerosol chemistry.
