Abstract : Burgers' equation is Fourier-analyzed to obtain a system of a discrete infinity of equations in a discrete infinity of variables. This system is studied numerically and the response to random initial conditions is obtained by use of a CDC 6600 digital computer. The 60 realizations obtained were used to obtain mean amplitudes, average energy spectra, skewness factors, flatness factors, and correlation functions. (Author)
