Uncertainty quantification of low - speed fan noise
Uncertainty quantification (UQ) has been achieved for the first time on the self-noise prediction of a low-subsonic axial fan. Realistic 5% and 4% errors are introduced on the volume flow-rate and the rotational speed, respectively, and a set of 81 ReynoldsAveraged Navier-Stokes (RANS) simulations of the fan mounted on an axisymmetric test plenum has been simulated at Clenshaw-Curtis points. By...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

Session 1pEAa: Active and Passive Control of Fan Noise 1pEAa1. Active control of axial and centrifugal fan noise
Both axial and centrifugal fans are used to cool information technology (IT) equipment. These fans generate noise that can be annoying to their users, particularly the tonal noise that can be radiated. Work has focused on developing a method to attenuate the tonal noise associated with both of these types of fans. A compact system is used, whereby control sources are placed in close proximity t...
متن کاملAn Integrated Fan Speed Control Solution Can Lower System Costs, Reduce Acoustic Noise, Power Consumption and Enhance System Reliability
Less than six years ago, thermal cooling in the electronics arena was mainly an issue for highperformance, high-end applications, such as, military, aerospace and large-scale industrial and medical applications. Outside these sectors, thermal cooling was just a premature notion. In the short span of a few years, technological and other developments have made thermal cooling necessary for many a...
