"Characterising Structures of Numerical Dissipation in Compressible Hydrodynamic Simulations of Turbulence"

Compressible hydrodynamic simulations of turbulence have applications including astrophysical modelling of star formation, and such simulations are simplified if numerical energy dissipation effects can act as a proxy for viscous forces. In an effort to further understanding of these effects, we implemented the kinetic energy equation to quantify and analyse the structure of this dissipation. I will discuss the fractal nature of turbulence and how these results parallel the structure observed in real-life turbulence. This is an ASC presentation by a PhB student.
