Introduction of Particle Image Velocimetry - UMD

random fluctuations correlation due to displacement peak: mean displacement. Influence of NI N I = 5 N I = 10 N I = 25 ... Spurious vectors Three main causes:-insufficient particle-image pairs-in-plane loss-of-pairs, out-of-plane loss-of-pairs-gradients. Effect of tracer density NNN
