3D PIV System

3D PIV system is based on the original 2D PIV system but uses the principle of stereoscopic imaging to add the third dimension. At least two sets of cameras view the test area from different angles and with the two sets of two-dimensional velocity vector components a third velocity vector component can be calculated within the test area. The image is first calibrated, and afterward this third velocity component can be evaluated.

Pressure Measurement PIV

  • Calculating accurate pressure from Particle Image Velocimetry (PIV) has long been a target of many fluid dynamics researchers.
  • MicroVec has implemented a software module to add determination of the pressure distribution to its PIV software. This implementation includes novel method called “Irrotational Correction on Pressure Gradient” (patent pending), which is unique and greatly improves the pressure reconstruction.

 

POD & DMD

  • Proper Orthogonal Decomposition (POD) is a statistical procedure of data analysis aimed at obtaining low-dimensional approximate descriptions of large scale, high-dimensional processes or data set.
  • Dynamic mode decomposition (DMD) is a new mathematical technique that allows t extract the dynamically relevant flow features from experimental or numerical data. In this technique, a linear mapping is constructed from a time resolved series of data. Microvec offers a DMD module.
