  2. Particle image velocimetry - Wikipedia

    en.wikipedia.org/wiki/Particle_image_velocimetry

    Particle image velocimetry (PIV) is a non-intrusive optical flow measurement technique used to study fluid flow patterns and velocities. PIV has found widespread applications in various fields of science and engineering, including aerodynamics, combustion, oceanography, and biofluids. The development of PIV can be traced back to the early 20th ...

    en.wikipedia.org/wiki/Stokes_number

    The Stokes number is defined as the ratio of the characteristic time of a particle (or droplet) to a characteristic time of the flow or of an obstacle, or. where is the relaxation time of the particle (the time constant in the exponential decay of the particle velocity due to drag), is the fluid velocity of the flow well away from the obstacle ...

    FIPS 201 (Federal Information Processing Standard Publication 201) is a United States federal government standard that specifies Personal Identity Verification (PIV) requirements for Federal employees and contractors. In response to HSPD-12, the NIST Computer Security Division initiated a new program for improving the identification and ...

  5. Particle tracking velocimetry - Wikipedia

    en.wikipedia.org/wiki/Particle_tracking_velocimetry

    The 3-D particle tracking velocimetry (PTV) belongs to the class of whole-field velocimetry techniques used in the study of turbulent flows, allowing the determination of instantaneous velocity and vorticity distributions over two or three spatial dimensions. 3-D PTV yields a time series of instantaneous 3-component velocity vectors in the form of fluid element trajectories.
