Hwa measurement of turbulent diffusion of a scalar quantity
Institute of Thermomechanics AS CR, v.v.i., Dolejškova 5, 182 00
The paper deals with simultaneous measurement of the velocity and the scalar quantity by means of hot-wire anemometry. Statistical moments of the scalar quantity fluctuations can be obtained employing a dual hot-wire probe. An evaluation procedure of the quantity mean values and fluctuations is described. Results from the molar concentration measurement in binary-gas mixture are shown.
