Abstract: The two-phase flow with nanoparticles (the solid liquid two-phase flow in which solid particles are from 1 nm to 100 nm) has been widely used in industries. A fundamental understanding of dynamics of nanoparticles in the flow is important and critical. In this study, a Particle Image Velocimetry (PIV) system has been developed to measure the movement of nanoparticles in the flow. The system utilises fluorescent core–shell SiO2 nanoparticles with a diameter around 55 nm as tracing particles. The error analysis of the system shows that the Brownian motion of particles plays a significant role in the accuracy of velocity measurements. By using the system, the velocity profile of nanoparticles in a channel flow is obtained and analysed.
