Motion of a gas in a cyclone heat exchanger

A semi-empirical theory of turbulence is used to obtain relations for calculation of the field of gas velocity in the flow core and boundary layer in a cyclone chamber. To close the system of Navier-Stokes equations, the apparent shear stress is represented in the form of the gradient dependence in circulation. The relations for calculating the tangential component of velocity were derived using experimental data on the qualitative character of the distribution of apparent shear stress over the radius of the cyclone.Translated from Inzhenerno-fizicheskii Zhurnal, Vol. 60, No. 2, pp. 277–284, February, 1991.
