ABSTRACT:
A velocimeter measures flow characteristics of a flow travelling through a chamber in a given direction. Tracer particles are entrained in the flow and a source of radiant energy produces an output stream directed transverse the chamber and having a sufficient intensity to vaporize the particles as they pass through the output stream. Each of the vaporized particles exploding to produce a shock wave and a hot core, and a flow visualization system tracks the motion of the hot cores and shock waves to thereby measure velocity of each tracer particle, and temperature of the flow around the tracer.
