摘要

Infrared thermal velocimetry is a new technique for the measurement of flow velocity. This non-intrusive technique was used to measure the velocity in a channel. In detail, a pulse of several milliseconds of a 5W CO_2 laser generates a transient temperature response in a flowing liquid. Recording the radiative thermal images of the moving heated liquid, permitted measurement of the flow velocity. This method has powerful characteristics; a wide range of velocities may be measured and the applications include MEMS fluidic devices. In this paper, experimental results are obtained from infrared thermal velocimetry for a syringe forced flow. Numerical results for the system are presented and compared with experimental data. Phenomena which are relevant to typical MEMS thermal flow sensors are also discussed.
