CFD Research

Hydraulic jumps are a phenomenon found in atmospheric flows. The main way of quantifying the jump is a shift in criticality (from super-critical to sub-critical) as measured by the Froude number. My research consisted of using open-source CFD software to recreate and analyze the phenomenon in order to determine how it would act with various width and narrowing parameters. Gerris and MITgcm were initially used for numerical solving while MATLAB was used to post-process and visualize the results. Gerris in particular ran all simulations that were used in the undergraduate thesis and implicit LES for handling turbulence as well as a Godunov scheme.
