Scattering of second sound waves by quantum vorticity

open access: yes, 1995
A new method of detection and measurement of quantum vorticity by scattering second sound off quantized vortices in superfluid Helium is suggested. Theoretical calculations of the relative amplitude of the scattered second sound waves from a single ...

Numeric and fluid dynamic representation of tornadic double vortex thunderstorms [PDF]

open access: yes
Current understanding of a double vortex thunderstorm involves a pair of contra-rotating vortices that exists in the dynamic updraft. The pair is believed to be a result of a blocking effect which occurs when a cylindrical thermal updraft of a ...

Vortex-Induced Micro-Cantilever Vibrations with Small and Large Amplitudes in Rarefied Gas Flow

open access: yesApplied Sciences
This study employs a fully coupled fluid–structure interaction (FSI) to investigate the vibrations of an elastic micro-cantilever induced by a rarefied gas flow.

Spectral simulation of unsteady compressible flow past a circular cylinder [PDF]

open access: yes
An unsteady compressible viscous wake flow past a circular cylinder was successfully simulated using spectral methods. A new approach in using the Chebyshev collocation method for periodic problems is introduced.

Turbomachinery [PDF]

open access: yes
The discipline research in turbomachinery, which is directed toward building the tools needed to understand such a complex flow phenomenon, is based on the fact that flow in turbomachinery is fundamentally unsteady or time dependent.

Aerodynamic Optimization Design of a Supergravity Centrifuge: A Low-Resistance Strategy

open access: yesApplied Sciences
Wind resistance optimization is crucial for enhancing the rotational speed of supergravity centrifuges. We conducted a study using computational fluid dynamics on the Centrifugal Hypergravity and Interdisciplinary Experiment Facility (CHIEF) under ...

Experimental Study of Isothermal Wake-Flow Characteristics of Various Flame-Holder Shapes [PDF]

open access: yes
An investigation of the isothermal wake-flow characteristics of several flame-holder shapes was carried out in a 4- by 4-inch flow chamber. The effects of flame-holder-shape changes on the characteristics of the Karman vortices and thus on the ...
