Abstract
In the paper the use of the thermal wave method for measuring flow velocity of air and carbon dioxide mixture is described. The research was conducted using a moving probe, placed in a closed chamber. A parallel configuration of the transmitter-detector configuration, with two wave detectors, was applied. A rectangular wave of 4Â Hz frequency was generated. By the use of the Fourier transform, the velocity of signals from the wave detectors was determined. Results for velocity of 10-50Â cm/s and carbon dioxide concentration up to 50% are shown in the paper.
