  • 3D Stereoscopic PIV —Internal wave investigations in the laboratory have been largely limited to two-dimensional and axisymmetric configurations. The ENDLab has recently utilized the flow field measurement technique of stereoscopic-PIV to study internal wave field in three dimensions. As a fruitful result, a wide range of experimental configurations are now possible for study. A detailed report of this study has been published in Experiments in Fluids.

  • Sailing on Diffusion — How can an object be propelled without any moving parts? New experimental and numerical results show how energy can be extracted from molecular diffusion to produce spontaneous propulsion. These results have potential significance for environmental and biological transport. [read more "Sailing on Diffusion"]
  • Lagrangian Coherent Structures — Understanding the transport of oil and debris is vital to environmental protection. By looking at the local deformation of the flow field, LCSs make it possible to identify the dominate structures that shape the overall flow and yield predictions on the movement of such contaminants. Through a review of past works, this article in Physics Today demonstrates the basis of LCSs and its future potential. [read more "Lagrangian Coherent Structures"]
