Abstract
In this article a statistical method for estimating the maximum instantaneous distortion values is developed further to estimate the maximum values of the instantaneous distortions in which the operation of peak values of dynamic pressures and correlation between them are involved. The effects of the correlation between fluctuating pressures on the estimation are discussed. Comparison between the estimated values and the experimental results shows that the developed method can quite accurately estimate the maximum value of the instantaneous distortion with operation of peak values of dynamic pressures involved, such as the distortion descriptor DC(sub theta). The accuracy estimation of maximum instantaneous distortion can generally be improved by considering the correlations between fluctuation pressures. However, when the mean correlation coefficient rho(bar) is less than 0.1, the estimation can be effected by dispensing with correlation. 4 refs.
