The frequency response of integrated thermal gas velocity detectors is estimated by means of 2-Dimensional finite element simulations. The study is devoted to examine the possibility to extend the application field of simple integrated flow meters to the detection of acoustic waves.

Abstract
The frequency response of integrated thermal gas velocity detectors is estimated by means of 2-Dimensional finite element simulations. The study is devoted to examine the possibility to extend the application field of simple integrated flow meters to the detection of acoustic waves. An original approach for taking into account non negligible heat conduction paths along the third axis is described. The role of the thermal mass of the active elements is highlighted.File in questo prodotto:
