Abstract: The diffusion of the fluid particles is one of the important fundamental problems of the research of transitional and turbulent flows. This phenomena is of great importance in case of pollutants spreading. In experimental study of the diffusion there is commonly used an admixture gas as a tracer, which enter the main airflow. The paper deals with the simultaneous measurement of the velocity and the molar concentration in binary-gas mixture by means of hot-wire anemometry. A special three-sensor probe has been manufactured and the calibration in Air-CO2 mixture is presented.
