Rotating Nonlinear Flows in Normal and Quantum Fluids

点击翻译按钮获取中文摘要

Non-Technical:This research award builds on unique expertize and experimentalfacilities at the University of Maryland to discover the properties ofrotating fluid flow in water and liquid helium. Turbulence in similarflows is important in engineering (in jet engines and pumps), stars, andin understanding the Earth's atmosphere and outer core. This projectwill also explore a strange type of motion at low temperature known as superfluidvortex turbulence. The overall goal of the research is to advance ourunderstanding of rotating fluid turbulence. The mentoring and training ofyoung researchers, as undergraduate and graduate students, is a criticalpart of this project. They will obtain professional skills asresearchers, preparing them for advancement as independent scientists towork in industry, national laboratories, or in research universities.Technical:This research award builds on unique experience and experimentalfacilities at the University of Maryland to probe shear driven flows inthe presence of rapid rotation in Newtonian fluids and superfluids.Turbulent flows with global rotation arise in engineering, astrophysical,and geophysical situations. This research funding allows work ondirectly visualizing superfluid vortex turbulence, in addition toexperiments in more easily diagnosable water flows. The overall goal ofthe research is to advance our understanding of a broad class ofphenomena involving the interaction of nonlinearity, rotation and, inpart, quantum fluids. The mentoring and training of young researchers, asundergraduate and graduate students, is a critical part of this project.They will obtain professional skills as researchers, preparing them foradvancement as independent scientists.
