Claim 0:
1. A tracer particle spreading device for a boundary layer flow visualization experiment based on a flat plate, the tracer particle spreading device comprising a tracer particle generator, smoke guiding tubes, a smoke storage box and a wall-surface particle distribution box, wherein:
the tracer particle generator comprises a fume and oil storage tank, a micro pump, a heating tube and a nozzle connected together in sequence;
the nozzle of the tracer particle generator is connected to the smoke storage box via the smoke guiding tubes;
the smoke storage box is configured for adjusting a flow speed of particles;
the wall-surface particle distribution box comprises a cavity, a rectifier plate mounted at a middle part of the cavity, and a thin wall cover plate provided at an upper part of the cavity and provided with particle spreading slits through which the particles escape; and
an outlet of the smoke storage box is connected to a lower part of the cavity via the smoke guiding tubes.
