THERMAL METHOD OF MEASUREMENT OF TURBULENCE IN WIND TUNNELS,
Abstract
The report discusses the general theory of diffusion in a turbulent flow and forms the basis of the method of measurement of turbulence in wind tunnels by studying the diffusion of heat behind a thin heated wire. Cited are results of measurements of temperature of velocity fields behind a round cylinder, conducted with a wide range of changes of relative distance from the cylinder. A description is given of the measuring equipment and basic results of investigations, connected with development of the method and technology of the experiment. Results of measurements by the thermal method are compared with other methods. In conclusion there are cited results of investigation of turbulence of flow in a number of wind tunnels by the thermal method. (Autor)
