Abstract On the basis of a Rayleigh scattering model for a single nanoparticle illuminated by a TEM00 laser beam, we theoretically and numerically study the speckle formation when nanofluids are illuminated by a TEM00 laser beam. The results show that the laser speckles possess a Gaussian distribution, which are in agreement with the experimental results. The results may be useful for using a laser speckle velocimetry to determine the velocitiies of nanoparticles in nanofluids.
