The invention provides a nanometer particle fluidizer and a supersonic velocity wind tunnel system. The nanometer particle fluidizer comprises a pressure storage tank, a first gas adjusting device and a combustion chamber. The pressure storage tank is used for containing turbid liquid which comprises combustible liquid, nanometer particles and macroparticles with the diameters larger than those of the nanometer particles. The first gas adjusting device is used for providing first gas and adjusting the flow of the first gas. The combustion chamber is used for providing a site for mixed combustion of the combustible liquid of the turbid liquid and the first gas, and the combustion chamber comprises a first inlet, a second inlet and an outlet, wherein the first inlet and the second inlet are connected with the pressure storage tank and the first gas adjusting device respectively, and the outlet is used for outputting second gas generated after the combustible liquid and the first gas participate in the combustion reaction under the pressure state. The supersonic velocity wind tunnel system comprises the nanometer particle fluidizer and a supersonic velocity wind tunnel communicated with the outlet of the combustion chamber of the nanometer particle fluidizer. The nanometer particle fluidizer is capable of achieving the adjustability of particle concentration, and the requirement for the nanometer particle concentration by an observation flow field can be well met.
