WebRayleigh disc to acoustical measurements has led several investigators to determine, by experiment, the magnitude of the small corrections to be applied for such of the departures from the ideal as are inevitably encountered in the use of the Rayleigh disc for calibrating microphones. In an account of the most recent Web(Rayleigh, 1878) As with Rayleigh, the entirely intellectual exercise of studying this problem is likely fulfilling. The system represents one of many examples of dynamic surface tension fluid flows. The relatively simple experimental results give rise to a rigorous mathematical representation that robustly explains the underlying phenomena.

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 … Web(Rayleigh, 1878) As with Rayleigh, the entirely intellectual exercise of studying this problem is likely fulfilling.

In this paper we will address both the fundamentals of the method and its applica-tion in inverse acoustics. Special attention will be paid to comparison between experimental results from PNAH, IBEM and the proposed method. INTRODUCTION
