Can Core Flows inferred from Geomagnetic Field Models explain the Earth's Dynamo? [PDF]
, 2015 We test the ability of large scale velocity fields inferred from geomagnetic secular variation data to produce the global magnetic field of the Earth.Our kinematic dynamo calculations use quasi-geostrophic (QG) flows inverted from geomagnetic field ...

Flow Field Analysis Around Pressure Shielding Structures [PDF]
AIAA AVIATION 2021 FORUM, 2021 The flow field around a series of streamwise rods, referred to as canopies, is investigated using two-dimensional two-component time-resolved particle image velocimetry (PIV) and large eddy simulations (LES) to characterize the changes in the flow field responsible for reducing the low and high-frequency surface pressure fluctuations previously ...

Inviscid transonic flow field analysis [PDF]
Proceedings of the Indian Academy of Sciences Section C: Engineering Sciences, 1981 This paper describes a method for analysing inviscid transonic flow. This method is based on the fact that the angle made by the streamline of the transonic flow and of the corresponding incompressible flow is usually small. By using curvilinear coordinates, the differential equation of the stream function of an inviscid compressible flow is simplified

Effect of an electric field on an intermittent granular flow [PDF]
, 2010 Granular gravity driven flows of glass beads have been observed in a silo with a flat bottom. A DC high electric field has been applied perpendicularly to the silo to tune the cohesion. The outlet mass flow has been measured.
