Transient thermal response of a hotwire anemometer

  title={Transient thermal response of a hotwire anemometer},
  author={Scott C Morris and J. F. Foss},
The ability of a thermal anemometry system to accurately measure unsteady fluid velocity depends on the electrical control system as well as the thermal properties of the sensor. The present work is a numerical study of the thermal transient response of a hot-wire. A conventional constant temperature anemometer with an ideal feedback amplifier as well as a pulse width modulated system were used to model the electrical current supplied to the sensor to maintain a nominally constant sensor… CONTINUE READING
