WT Aerospace Engineering

I am Samuel "Red" Otto. This blog documents my progress on projects in propulsion and CFD. In Research Science with Graig Marx, my focus is on the regression behavior of liquefying hybrid rocket fuels, determining the dependence of regression rate coefficients on the Thermal Properties of n-paraffin fuels. In ACSI with David Nassar, I am investigating core flows in a hybrid rocket motor using a MUSCL scheme in conjunction with the Advection Upstream Splitting Method (AUSM) for flux evaluation.
