Popis: In the present article, the heat transfer coefficient was determined experimentally when a subsonic jet flows onto a plate. The jet escaped from axisymmetric nozzles with a diameter of d = 290, 540, and 980 μm. The experiments were carried out at the speeds of V = 5, 20, 40, 60, 80 and 100 m/s in the Reynolds numbers range of 100 – 7000. The Nusselt number distribution was obtained for different distances between the nozzle and cooled surface.
