| contents | In this article, we attempt to understand various aspects of turbulent flows in electron hydrodynamics. We analyze a rectangular channel geometry in the presence of an electric field and a Corbino geometry in the presence of a magnetic field. In the former geometry, we analyze the conductivity of the fluid as well as the frequency spectrum of perturbations about the Poiseuille flow. While the normal Poiseuille flow has an associated conductivity which scales as $W^2$, we find a correction which scales as $W^4$ in the case of non-linear flows, where $W$ is the characteristic length of the system. In the Corbino geometry, we analyze the velocity, vorticity and magnetic fields. We find that the vorticity can span across a wide range near the edge of the geometry, a behavior that can be reflected in the velocity and magnetic fields. |
