By the means of experiments and numerical simulations, it is verified that speckles can be formed when nanofluids are illuminated by laser beam. First, clear speckles are formed by illuminating static nanofluids containing proper volume fraction of nanoparticles. Then, classic-scattering-model and photon-nanoparticle-collision-model are respectively established based on the wave-particle duality of light. The formation of speckles with nanofluids is simulated respectively on these two models, and the formation mechanism of speckles is figured out.
