4-D Particle Tracking Velocimetry Applied to Gas-Liquid Reactors
In the chemical industry, many process operations depend on complex multi-phase flow processes. Apart from the transport of fluids through pipelines or vessels, flow processes in combination with chemical reactions, heat and mass transfer are of crucial importance. Detailed knowledge of the local parameters becomes more and more important with increased development levels of process operation. ...
متن کاملSingle-camera, three-dimensional particle tracking velocimetry.
This paper introduces single-camera, three-dimensional particle tracking velocimetry (SC3D-PTV), an image-based, single-camera technique for measuring 3-component, volumetric velocity fields in environments with limited optical access, in particular, optically accessible internal combustion engines. The optical components used for SC3D-PTV are similar to those used for two-camera stereoscopic-µ...
متن کاملDefocusing digital particle image velocimetry and the three-dimensional characterization of two-phase flows
Defocusing digital particle image velocimetry (DDPIV) is the natural extension of planar PIV techniques to the third spatial dimension. In this paper we give details of the defocusing optical concept by which scalar and vector information can be retrieved within large volumes. The optical model and computational procedures are presented with the specific purpose of mapping the number density, t...
متن کامل1 Two - Color Particle Tracking Velocimetry and Thermometry
Particle Tracking Velocimetry (PTV) and Particle Image Velocimetry (PIV) originally have been established for velocity field visualization. In the meantime flow fields of interest in classical and applied fluid mechanics are essentially inseparable from thermal effects in the majority of cases. Different physical phenomena are involving for temperature field mapping depending on physical proper...
متن کاملApplying Feature Tracking to Particle Image Velocimetry
Particle Image Velocimetry (PIV) is a popular approach to flow visualisation and measurement in hydroand aerodynamic studies and applications [7]. The fluid is seeded with particles that follow the flow and make it visible. Traditionally, correlation techniques have been used to estimate the displacements of the particles in a digital PIV sequence. Recently, we have successfully applied to PIV ...
