In an axial fan, a leakage flow driven by a pressure gradient between the pressure side and
the suction side occurs in the gap between the shroud and the casing. This leakage flow is …

The tip leakage noise generated by a shrouded rotor of an axial-flow fan has been
experimentally studied. The measurements have been taken at high flow rate and at the …

Axial flow fans are used in many fields in order to ensure the mass and heat transfer from air,
chiefly in the heating, ventilation and air conditioning industry (HVAC). A more proper …

The paper presents a methodology for on-site investigation of short-ducted industrial axial
flow fans, as an easily realizable and effective means for concerted diagnostics on fan …

The paper outlines the development of a new radial fan family for performing relatively high
flow rate for gases laden with solid impurities in technological processes. The paper …

This paper presents comparative data on the aerodynamic lift and drag of basic model
representations of low-speed axial fan blade sections. Three main types of blades are …

The paper presents wind tunnel experiments, supplemented with phased array microphone
measurements, on 2D basic models of low-speed axial fan blade sections: a flat plate, a …

The paper reports on establishing a beamforming dataset, relying on the phased array
microphone (PAM) technique, on the broadband noise of rectilinear basic models of low …

Operation of electric drives in agroindustrial complex shows that it is necessary to know how
the parameters of electric motor cooling system change with changes in rotor speed, air flow …

The noise emission of low speed turbomachinery, including axial flow fans, has been the
topic of recent research for multiple reasons. First, these machines often operate in the close …
