✦ Synopsis
Measurements were taken on.[our oil/air or gas/air d([]itsion.[tames to ineestigate the connection hetweenJtuetuations in air velocitl' in or near the/tame -one,fluctuations in burning rate and combustion noise output. In all cases the combustion noise spectrum wasJound to be approximateO, 6 dB per octave up on the spectrum of air i,elocity.[tuetuations. The simple model o['the noise generation mechanism suggested hi" this result was not supported h)' measurements on burning rate [tuctuations.
However, in almost all cases the tran,~/~,r Jimetions between .fluctuations in air t~elocity, burning rare and sound output could he expressed a.s a junction q/fi'equencl' hv a simple power htw.
