In experimental study of the diffusion there is commonly used an admixture gas as a tracer that enters the main airflow. The paper deals with the simultaneous measurement of the molar concentration in binary-gas mixture by means of hot-wire anemometry. A special three-sensor probe has been manufactured and used for this task. A case of polynomial shaped 2D hill with the line source of tracer gas has been studied in detail. Geometry of the hill was taken from Almeida at al. Experimental study of the binary-mixture concentration field over the hill has been done.
