Rayleigh disk experiment
WebThe Rayleigh disc method has long been used for calibrating microphones. It has recently been criticized as being inaccurate both fundamentally and experimentally [I]. In this paper, techniques are outlined for improving the ease of calibration of the suspension, for rendering the optics more efficient and overcoming drifting from resonance.

WebWe present a numerical study of axisymmetric flow in a rotating annulus in which local thermal forcing, via a heated annular ring on the outside of the base and a cooled circular disk in the centre of the top surface, drives convection. This new configuration is a variant of the classical thermally-driven annulus, where uniform heating and cooling are applied … WebFeb 20, 2024 · A lightweight disk turns perpendicular to the air flow.Meiners' explanation: "in any other position of the disk in relation to the flow, the lines of air flo...
