Title: Numerical study of radial high-pressure blower with frequency converter Keywords: Numerical study, CFD, radial high-pressure blower, frequencyAbstract: Radial high-pressure air blowers are used when it is necessary to transfer air mass from one area to another
accompanied by generation of significant pressure in a short period of time. In practice, this is used in case of need for
rapid extraction of contaminated air or in general in the industry for intensive blowing or sucking air from or in rooms with
special requirements for air quality in them. The aim of this work is to consider the specific geometry of a radial highpressure
air blower, model S-HP 470/35 - 105/20 from Elektror airsystem Gmbh, for which detailed measurements
according to DIN EN ISO 5801 Fans - Performance testing are made. As a result of the measurements made for this
particular blower, a detailed ventilation characteristic curve is created. The selected range for validation of the numerical
results compared to the experimental measurements coincides with the range of ventilation characteristic curve from
0m3/min to 48.2 m3/min. References - R. K. Turton, “Principles of Turbomachinery”, Book, Springer Netherlands, ISBN: 978-94-010-9691-1, https://doi.org/10.1007/978-94-010-9689-8, 1984.
