PIV

PIV, or Particle Image Velocimetry, is a method used by scientists to visualize and measure the flow of liquids or gases. It involves seeding the fluid with tiny particles that follow the flow. Using a laser sheet and a camera, the particles are illuminated and recorded at different times. By analyzing how the particles move between images, researchers can accurately determine the velocity and direction of the flow. PIV is widely used in engineering, aerodynamics, and fluid dynamics research to gain detailed insights into complex flow behaviors.
