PIVjärjestelmissä
PIVjärjestelmissä refers to the implementation or use of PIV systems. PIV, or Particle Image Velocimetry, is a non-intrusive optical technique used for fluid flow measurement. It provides instantaneous velocity field measurements in a plane. The system typically consists of a light source, usually a laser, which illuminates a thin plane within the flow. Seeding particles are added to the fluid, which are assumed to follow the flow accurately. A digital camera captures images of these particles at two different time instances, separated by a known short interval. By analyzing the displacement of particle patterns between the two images, the velocity of the fluid can be determined.
In the context of PIVjärjestelmissä, the focus is on the practical aspects of setting up and operating
