Abstract

An integrated method for designing high-pressure main ventilation and forced-draft fans is presented. To do this, at the first phase, mathematical models are used to determine the main geometric characteristics of the fan flow path and its integral characteristics. At the second phase, the improvement of the spatial shape of the fan flow path is performed. The approach is implemented as an automated complex with the possibility of subsequent data transfer to third-party CAD / CAM / CAE systems. Using the proposed approach, a high-pressure VO-32DN fan was created, whose main characteristics significantly exceed those of the fans of this class.
