Compact Integrated Active-Passive Approach for Axial Fan Noise Control
… for the control of noise radiated from a small axial fan was investigated. The approach involved the installation of an axial fan into a short duct with both passive and active noise control functions. First, a systematic methodology for the analytical modeling of finite-length ducts with …

Design Optimisation and Flow Characterisation for Future Aeroengine Axial Fan Blades
… efficiency optimisation of a modern jet engine fan blade with constrained pressure ratio. This outcome is compared against a state-of-the-art adjoint-based approach. Results indicate the strategy proposed achieves comparable improvements to its adjoint counterpart with a reduced computational …

Computational fluid dynamic based optimisation of an industrial axial fan for rapid prototyping
Axial air flow fans are widely used for air movement. In an increasingly international and competitive market, smaller fan companies find themselves in need of rapid preliminary design. This need is addressed in this study through the development of a first-revision, Computational Fluid Dynamics …

Using Motor Electrical Signature Analysis to Determine the Mechanical Condition of Vane-Axial Fans
… of this research was a proof of concept using a fan motor stator as transducer to monitor motor rotor and attached axial fan for mechanical motion. The proof was to determine whether bearing faults and fan imbalances could be detected in vane-axial fans using Motor Electrical Signature Analysis …

Fluvial sedimentation in continental half-graben basins
… points of sediment and water that produced an axial fan and longitudinal channel flanked by transverse fans. Imposition of various combinations of lateral and axial sediment flux showed that the locations and widths of the deposits were controlled by relative sediment discharges and not by the …

Error Sensor Placement for Active Control of an Axial Cooling Fan
… in active noise control (ANC) for cooling fans have used near-field error sensors whose locations are determined according to a theoretical condition of minimized sound power. A theoretical point source model, based on the condition previously stated, reveals the location of near-field …
