Greenland flow variability from ice-sheet-wide velocity mapping
Using RADARSAT synthetic aperture radar data, we have mapped the flow velocity over much of the Greenland ice sheet for the winters of 2000/01 and 2005/06. These maps provide a detailed view of the ice-sheet flow, including that of the hundreds of glaciers draining the interior. The focused patterns of flow at the coast suggest a strong influence of bedrock topography. Differences between our t...
متن کاملFlow Field Abstraction and Vortex Detection for MR Velocity Mapping
The evolution of blood flow patterns (vortical flow features in particular) and their interactions with cardiovascular structure is important in the study of cardiovascular function. The winding index method is widely used for vortex detection and has shown to be very sensitive to noise. We propose a novel technique for the detection of vortical flow features that consists of three main compone...

A mathematical model for blood flow in the small blood vessel in the presence of magnetic field is presented in this paper. We have modeled the two phase model for the blood flow consists of a central core of suspended erythrocytes and cell-free layer surrounding the core. The system of differential equations has been solved analytically. We have obtained the result for velocity, flow rate and ...
متن کاملCellular flow in a small blood vessel
In the smallest capillaries, or in tubes with diameter D 8 μm, flowing red blood cells are well known to organize into single-file trains, with each cell deformed into an approximately static bullet-like shape. Detailed high-fidelity simulations are used to investigate flow in a model blood vessel with diameter slightly larger than this: D=11.3 μm. In this case, the cells deviate from this sing...
