3D Visualization of the separated fluid flows

Journal of Visualization, 2004
For the detailed investigation of the 3D unsteady incompressible viscous separated fluid flows around a sphere (for 200 ≤ Re ≤ 700) and a circular cylinder (for 200 ≤ Re ≤ 400) the direct numerical simulation and 3D visualization are used. For 3D visualization of the fluid flows around a sphere the definition of vortex core as a connected region ...

Microscale 3D flow mapping with μDDPIV

Experiments in Fluids, 2007
Three-dimensional (3D) quantitative flow visualization by tracking microscale particles has become an invaluable tool in microfluid mechanics. Defocusing digital particle image velocimetry (DDPIV) can recover spatial coordinates by calculating the separation between defocused images generated by an aperture mask with a plurality of pinholes.

On 3D scene flow and structure estimation

Proceedings of the 2001 IEEE Computer Society Conference on Computer Vision and Pattern Recognition. CVPR 2001, 2005
In this paper, novel algorithms computing dense 3D scene flow from multiview image sequences are described. A new hierarchical rule-based stereo matching algorithm is presented to estimate the initial disparity map. Different available constraints under a multiview camera setup are investigated and then utilized in the proposed motion estimation ...

3D manipulation and dynamics of soft materials in 3D flows

Journal of Rheology, 2023
Flow-based manipulation of particles is an essential tool for studying soft materials, but prior work has nearly exclusively relied on using two-dimensional (2D) flows generated in planar microfluidic geometries. In this work, we demonstrate 3D trapping and manipulation of freely suspended particles, droplets, and giant unilamellar vesicles in 3D flow ...

Ricci Flow for 3D Shape Analysis

2007 IEEE 11th International Conference on Computer Vision, 2007
Ricci flow is a powerful curvature flow method in geometric analysis. This work is the first application of surface Ricci flow in computer vision. We show that previous methods based on conformal geometries, such as harmonic maps and least-square conformal maps, which can only handle 3D shapes with simple topology are subsumed by our Ricci flow based ...

3D Flow Reactors: Flow, Hydrodynamics, and Performance

Industrial & Engineering Chemistry Research, 2014
A device comprised of a sequence of converging or diverging units aligned either in an axisymmetric or nonaxisymmetric manner can be used as a continuous flow reactor. Here we report the analysis of flow and hydrodynamics (pressure drop, residence time distribution, and mass transfer) for an axisymmetric geometry of a 3D flow reactor for single phase ...

3D contour perception for flow visualization

Proceedings of the 3rd symposium on Applied perception in graphics and visualization, 2006
One of the most challenging problems in data visualization is the perception of 3D flow fields because judging the orientation of 3D paths is perceptually difficult. It is hypothesized that perception of the orientations of streamlines in space can greatly benefit from stereoscopic depth cues and motion parallax. In addition, because stereoscopic depth

Ultrasound flow mapping of 3D turbulent liquid metal flows

2017 IEEE International Ultrasonics Symposium (IUS), 2017
Flows in metallic melts can be driven by magnetic fields, which is a branch of magnetohydrodynamics (MHD). Crystal growth processes can profit from magnetically driven flows, since it can optimize the mass and heat transfer in the melt and thereby improve the structural and electrical properties of the grown crystals.
