Stereo Thermal Marking Velocimetry
This paper presents a novel approach to measuring and mapping shape and motion of the water surface. The approach combines and borrows from existing techniques, such as stereo imaging shape recognition and tracking, infrared (IR) laser marking and thermography, and particle image velocimetry. The system consists of a high power IR laser beam controlled by a programmable marking head and two IR ...
متن کامل3D Particle Tracking Velocimetry using a Stereo Camera Setup
In this thesis, we describe an approach for measuring fluid flows by means of particle tracking velocimetry with a stereo camera system. Building upon an existing hardware setup, originally used for 2D velocimetry, we developed a new system for depth recovery and interactive visualization of particle trajectories, in cooperation with our industry partner Airbus Deutschland GmbH. The application...
متن کاملLaser-induced thermal-acoustic velocimetry with heterodyne detection.
Laser-induced thermal acoustics (LITA) was used with heterodyne detection to measure simultaneously and in a single laser pulse the sound speed and flow velocity of NO>(2) -seeded air in a low-speed wind tunnel up to Mach number M =0.1 . The uncertainties of the velocity and the sound speed measurements were ~0.2 m/s and 0.5%, respectively. Measurements were obtained through a nonlinear least-s...
متن کاملDistributed Processing of High-speed Stereo Particle Image Velocimetry Data with a Low Power Beowulf Cluster
In this paper, we present our design of a portable cluster supercomputer created specifically for processing PIV image data. To make the system portable for a laboratory environment, the cluster computer is required to run on minimal power and be light weight. The final cluster design was based on the Intel R ©QuadCore Xeon R ©X3210 low-power processors. This hardware setup allows for a total s...
متن کاملEffective visualization of stereo particle image velocimetry vector fields of a turbulent boundary layer
Stereo particle image velocimetry datasets contain three-dimensional information over a plane, from which multiple quantities can be derived at each point. The task of visualizing these different parameters simultaneously is challenging, and this inhibits our ability to analyse and derive firm conclusions about the physics of the flow. Currently, the common approach is to view each parameter se...
