Slip Correction Factor for Gas Diffusion

In the first summer of the COVID-19 pandemic, I worked on a research project with my father, Carlos Coimbra, who is a mechanical engineering professor at UC San Diego. My goal was to find the analogies between molecular and aerosol diffusion for small, non-spherical particles. I discovered a simple but remarkably accurate relationship for estimating binary coefficients for monoatomic, diatomic, and triatomic gases diffusing in air. This work eventually resulted in a first-author paper in the AIAA journal. Through this research project, I learned about transport properties and developed data analysis skills, such as nondimensionalizing expressions, finding correlations, and organizing data via data spreadsheets and curve-fitting. 

The paper was accepted in the AIAA journal on April 4, 2022.
