Full Form: Particle Image Displacement Velocimetry
For more information of "Particle Image Displacement Velocimetry", see the section below.
Principle of PIDV
PIDV involves illuminating the fluid with a laser light sheet and capturing a sequence of images of the illuminated particles using a high-speed camera. By analyzing the displacement of the particles between consecutive images, the velocity of the fluid can be calculated.
Advantages of PIDV
- Non-intrusive: PIDV does not require any contact with the fluid, making it ideal for measurements in sensitive or inaccessible environments.
- High spatial and temporal resolution: PIDV can provide velocity measurements with high spatial and temporal resolution, enabling detailed flow analysis.
- Versatile: PIDV can be applied to a wide range of fluids, including liquids, gases, and multiphase flows.
Applications of PIDV

- Fluid dynamics: Studying flow patterns, turbulence, and boundary layers.
- Biomedical engineering: Measuring blood flow in vessels and tissue.
- Environmental engineering: Investigating pollutant dispersion and water currents.
- Industrial applications: Optimizing fluid flow in pipelines, pumps, and other industrial equipment.
Essential Questions and Answers on Particle Image Displacement Velocimetry in "MISCELLANEOUS»UNFILED"
What is Particle Image Displacement Velocimetry (PIDV)?
Particle Image Displacement Velocimetry (PIDV) is a non-intrusive optical measurement technique used to measure the velocity of a fluid by tracking the displacement of tracer particles suspended in the fluid.
How does PIDV work?
PIDV involves illuminating the fluid with a laser sheet and capturing a sequence of images using a high-speed camera. The movement of the tracer particles is tracked between consecutive images, and the velocity is calculated based on the displacement of the particles.
What are the applications of PIDV?
PIDV is widely used in various fields, including:
- Fluid dynamics research (e.g., turbulence, boundary layers)
- Industrial flow measurements (e.g., in pipelines, ducts)
- Biomedical applications (e.g., blood flow visualization)
- Environmental studies (e.g., flow patterns in rivers)
What are the advantages of PIDV?
Advantages of PIDV include:
- Non-intrusive and does not disturb the flow
- Provides velocity measurements over a large field of view
- High spatial and temporal resolution
- Suitable for measurements in opaque fluids and complex geometries
What are the limitations of PIDV?
Limitations of PIDV include:
- Requires proper seeding of tracer particles in the fluid
- Can be affected by particle settling and agglomeration
- Not suitable for flows with high particle concentrations or large particle sizes
How does PIDV differ from other velocity measurement techniques?
PIDV is distinguished from other techniques such as Particle Image Velocimetry (PIV) by its ability to measure the displacement of individual particles directly, rather than relying on cross-correlation techniques. This allows PIDV to provide more accurate velocity measurements at lower particle concentrations and in flows with complex velocity gradients.
Final Words: PIDV is a powerful tool for measuring fluid velocity with high accuracy and resolution. Its non-intrusive nature and versatility make it suitable for a wide range of applications in fluid dynamics, biomedical engineering, and other fields.
