The results of experimental investigations relevant to the influence of Reynolds number on non-self-similarity of flow in the annular channel with cyclone generator of turbulent. Areas of mean and pulsating velocities have been studied with the help of laser Doppler anemometer at the value of Reynolds number Re = 770... 10,9 • 103 (Re = Fcp/J3v, Vcp - mean air velocity in the annular channel, v - coefficient of kinematic viscosity).Equations and recommendations for calculation of basic aerodynamic characteristics of turbulent flow in the annular channels of heat exchange units.
