What are the Challenges in Using PIV for Catalysis?
While PIV is a powerful tool, it comes with certain challenges: - Particle Selection: Choosing appropriate tracer particles that are neutrally buoyant and reflective enough to be captured by cameras can be difficult. - Optical Accessibility: Catalytic reactors are often opaque or have complex geometries, making it challenging to achieve good optical access for laser illumination and image capture. - Data Processing: Processing large sets of high-resolution images requires significant computational resources and expertise in image analysis. - Interference from Reactions: In some cases, the chemical reactions may produce by-products that interfere with the PIV measurements, complicating data interpretation.
