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.
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 high accuracy 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 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
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 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.
