Studying Equalization of the Radial Fan’s Discharge Flow

Hulai, B. / Dovbush, O. / Piznak, B. / Kasynets, M.

Abstract It has been established that the qualitative parameters of the non-uniformity of the radial fan’s discharge flow are energy parameters such as coefficients of kinetic energy and the amount of motion. Compared with the ratio of maximum velocity to the average one, in the case of backflows, the specified indicators reflect the flow characteristic throughout its section. It has been proposed to determine the pressure loss in the diffusers located behind the radial fan, that is, with the non-uniform distribution of the velocities at the inlet, and with the uniform distribution of the velocities at the outlet, using the change in the kinetic energy coefficient.
