Using Motor Electrical Signature Analysis to Determine the Mechanical Condition of Vane-Axial Fans
… 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 (MESA). The data was statistically analyzed to determine if the MESA …

Aeroacoustic transfer of leading edge serrations from single aerofoils to low-pressure fan applications
… data basis is then used to design low-pressure axial fans of minimum complexity by keeping the initially chosen aerofoil type. The experimentally identified noise reduction mechanisms for the serrated axial fans are found to be more diverse than the single aerofoil and highly dependent on the …

Micro-climate modelling and engineering design for a horticultural grow-cell prototype
… example i.e. a 2 m × 1 m × 2 m chamber with two axial fans, a heating element, and an array of thermocouples. In this case, the modelling approach yields Hammerstein type models which are subsequently used for both single and multi–zone control system design. The laboratory facility was used for …

Bio-Inspired Axial Fan Design, 3D Printing Fabrication and Characterization for Noise and Flow Performance Optimization
… acoustic regulations. In this context, axial-flow fans represent a key technological component, acting as major sources of both tonal and broadband aerodynamic noise, with direct implications for public health, building energy performance, and urban liveability. Mechanical fans, …

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 …
