- A new standard Particle Image Velocimetry software with direct cross-correlation method will make a lead to high accuracy measurement and smooth flow visualization.
- 2D.ver* two component u(x) v(y) in 2D planar domain
- 3D.ver * three component u(x) v(y) w(z) in 2D planar domain
- Velocity, Standard Deviation, Reynolds Stress, Vorticity, Turbulent Kinetic Energy are analyzable
- Flownizer instantly processes the sequential image provided from all kinds of photographic instruments
* What is PIV?
PIV (Particle image velocimetry) is an optical method used in fluidics fields to analyze instant vector velocity by measuring minute change of generous fine particle image that traces the motion of the flow accurately in the image.
* PIV Software
Flow Analyzer 2D (a PIV 2D2C software including PTV 2D2C) and Flow Analyzer 3D (a PIV 2D3C) are useful in all kinds of flow visualization experiments in such example like wind tunnel, water tank, heat transfer, river, blood current.
User example case in:
* Air current, wind tunnel experiment
Flow around structures, car bodies, airfoil
* Water tank and channels in the lab
Flow around water structures, boats and ships, propeller
Cavitation flow and Hydrological experiment
* Microscope/Micro PIV
Blood current or movement of microorganism
Micro-bubble
Details
* PIV 2D-2C
- Measurement of 2 component velocity vectors in a 2D planar domain based on high image density Particle Image Velocimetry, which tracks small group of particle
* PTV 2D-2C
- Measurement of 2 component velocity vectors in a 2D planar domain based on particle tracking velocimetry, which tracks individual particle
* PIV 2D-3C
- Measurement of 3 component velocity vectors in a 2D planar domain based on stereoscopic Particle Image Velocimetry
* Calibration
- Flow Analyzer supports the grid calibration method/and provides high accuracy data.
- The calibration of Flow Analyzer corrects the lens distortion and transforms XY data in 2D projection (XYZ data in 2D3C)
* Preprocessing
- Masking function will keep you free from unnecessary area's that will cause error vector.
- Preprocessing tools such as background differencing technique, filters and arithmetic will help you modify bad original images to analyzable images
* Correlation Coefficient Map
- Flow Analyzer has an excellent animation preview function for the correlation coefficient map and other information.
- The dialogue displays interrogation window image, search window image and the color map of correlation coefficient in this two images
* Data analysis
- Abounding result item such as Raw vectors, Average, Angles, Stream line, Streak line, Path line, Vorticity, Turbulent kinetic energy, Reynolds stress, Velocity gradient tensor, Standard deviation, Velocity gradient tensor can be visualized.
