Mixing in stratified gravity currents: Prandtl mixing length

Autor: Odier, Philippe, Chen, Jun, Rivera, Michael K., Ecke, Robert E.

Shear-induced vertical mixing in a stratified flow is a key ingredient of thermohaline circulation. We experimentally determine the vertical flux of momentum and density of a forced gravity current using high-resolution velocity and density measureme

Eulerian and Lagrangian velocity statistics in weakly forced two-dimensional turbulence

Autor: Rivera, Michael K., Ecke, Robert E.

We present statistics of velocity fluctuations in both the Lagrangian and Eulerian frame for weakly driven two-dimensional turbulence. We find that simultaneous inverse energy and enstrophy ranges present in the Lagrangian and Eulerian Fourier spectr

Lagrangian statistics and coherent structures in two-dimensional turbulence

Autor: Rivera, Michael K., Daniel, W. Brent, Ecke, Robert E.

Measurements of Lagrangian single-point and multiple-point statistics in a quasi-two-dimensional stratifed layer system are reported. The system consists of a layer of salt water over an immiscible layer of Fluorinert and is forced electromagneticall

The Inverse Energy Cascade of Two-Dimensional Turbulence

Autor: Rivera, Michael K.

This thesis presents an experimental study of the inverse energy cascade as it occurs in an electromagnetically forced soap film. It focuses on characterizing important features of the inverse cascade such as it's range, how energy is distributed ove
