PIV is implemented in catalysis studies by following these general steps: 1. Seeding the Fluid: The fluid within the catalytic reactor is seeded with tracer particles that are small enough to follow the flow without altering it. 2. Illuminating the Flow: A laser sheet is used to illuminate the seeded particles. The laser provides a high-intensity light source that allows the particles to be clearly visible in the captured images. 3. Capturing Images: High-speed cameras capture multiple images of the illuminated particles at different time intervals. 4. Image Processing: The captured images are processed using cross-correlation algorithms to calculate the displacement of particles between successive frames. 5. Velocity Field Calculation: The displacement data is used to compute the velocity field of the fluid, providing a detailed map of flow patterns within the reactor.
