Wavelet Transform Analysis of Unsteady Turbulence and Turbulent Burning Velocity in a Constant-Volume Vessel

Abstract

The determination of the turbulence parameters is a difficult and important problem for combustion analysis. In this study, we propose a newly developed method of defining unsteady turbulence intensity in order to examine the relation between the turbulence characteristics and the burning velocity of turbulent flame propagating in homogeneous fuel-air mixture. We use the discrete wavelet transform, which is a time-frequency analysis method for calculating unsteady turbulence intensity and use a complex-type mother wavelet, the RI-Spline wavelet as the mother wavelet. Our experiments demonstrate the merits of our approach.
