An important issue for the aeronautical industry is the reduction of aircraft noise. The rotor–stator interaction is a predominant part of the noise emission. Presented are an introduction to these interaction theories, whose applications are numerous. For example, the conception of air-conditioning ventilators requires a … See more As the source levels can't be easily modified, it is necessary to focus on the interaction between those levels and the noise levels . The transfer function Where M is the See more • Sijtsma, P.; Schulten, J.B.H.M. (2003). "Wake modelling accuracy requirements for prediction of rotor wake-stator interaction noise (NLR-TP-2003-124; AIAA Paper 2003-3138)" See more The minimization of the transfer function $${\displaystyle {{F_{m}} \over {P_{m}}}}$$ is a great step in the process of reducing the noise emission. … See more All this study was made for a privileged direction : the axis of the rotor–stator. All the results are acceptable when the noise reduction is ought to be in this direction. In the case where the noise to reduce is perpendicular to the axis, the results are very different, as … See more WebFeb 12, 2024 · In a typical batch process, 120 g of bulk hBN microparticles, 12 g of ethyl cellulose (4 cP viscosity grade, Sigma-Aldrich), and 800 mL of ethanol were shear-mixed at 10,230 rpm for 2 h, using a rotor/stator mixer (L5M-A, Silverson) with a square hole screen.
