2D/3D PIV software [Flownizer]
A new standard 2D2C/2D3C PIV software
Flownizer2D/3D[Particle Image Velocimetry]
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 such as high speed camera/double shutter camera/video camera into digital data with a brand new computer architecture.
Flownizer fits perfectly to all velocimetry as follows.
*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.
Blood flow or movement of microorganism.
Measurement of 2 component velocity vectors in a 2D planar domain based on high image density Particle Image Velocimetry, which tracks small group of particles.
Measurement of 2 component velocity vectors in a 2D planar domain based on particle tracking velocimetry, which tracks individual particle.
Measurement of 3 component velocity vectors in a 2D planar domain based on stereoscopic Particle Image Velocimetry.
Flownizer supports the grid calibration method and provides highly accurate data.
The calibration of Flownizer corrects the lens distortion and transforms XY data in 2D projection (XYZ data in 2D3C).
Masking function will keep you free from unnecessary areas that will cause error vectors.
Preprocessing tools such as background differencing technique, filters, and arithmetic will help you modify poor quality original images to analyzable images.
Correlation Coefficient Map
Flownizer 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.
Abounding result items 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.
