velocimetry การใช้

• The Lorentz force velocimetry was invented by the A . Shercliff.
• This technology is also known as acoustic Doppler velocimetry.
• A Lorentz force velocimetry system is called Lorentz force flowmeter ( LFF ).
• The force measurement system is an important part of the Lorentz force velocimetry.
• Other techniques used to measure flows are laser Doppler velocimetry and hot-wire anemometry.
• Optical techniques are frequently used in modern fluid velocimetry but most are opto-mechanical in nature.
• In molecular tagging techniques, like in PIV, velocimetry is based on visualizing the tracer displacements.
• This technology can be paired with particle image velocimetry ( PIV ), which detects instantaneous velocity data.
• Indirect measurements can be performed by a tracer, repeated channel surveys, bedform velocimetry, or velocimetry.
• Indirect measurements can be performed by a tracer, repeated channel surveys, bedform velocimetry, or velocimetry.
• Impact events are typically recorded with high-speed video / film, or Particle Image Velocimetry ( PIV ).
• Laser Doppler Velocimetry predates PIV as a laser-digital analysis system to become widespread for research and industrial use.
• Time-of-flight Lorentz force velocimetry, is intended for contactless determination of flow rate in conductive fluids.
• The present-day applications are almost innumerable and include image analysis, image compression, velocimetry, and strain estimation.
• Another field of application is nonlinear ultrasonic velocimetry, one order of magnitude more precise than with the usual Doppler effect.
• PIV itself found its roots in Laser speckle velocimetry, a technique that several groups began experimenting with in the late 1970s.
• Other Molecular tagging velocimetry ( MTV ) methods have used ozone ( O3 ), excited oxygen and nitric oxide as the tag instead of hydroxyl.
• Another well-developed and widely documented technique that yields extremely high accuracy is "'Hydroxyl tagging velocimetry "'( HTV ).
• Nd : YAG lasers can also be used for flow visualization techniques in fluid dynamics ( for example particle image velocimetry or laser-induced fluorescence ).
• Particle image velocimetry methods will in general not be able to measure components along the z-axis ( towards to / away from the camera ).
