Turbulent diffusion of passive impurity in gas suspension at large reynolds numbers

Experimental results on the turbulent diffusion of passive impurity in a gas-suspension flow in a vertical cylindrical channel are outlined. On the basis of introducing simple approximations of spectral functions of the velocity pulsations, the influence of the discrete phase on the turbulent diffusion coefficient is estimated.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 59, No. 4, pp. 631–634, October, 1990.
