Abstract : Statistical analysis, which has found increasing use in the solution of complex problems in recent years, is presented in a form suitable for subsonic turbulent flow investigation. A computer program, designed for the CDC 6600 and written in FORTRAN IV, is the core of the analytical process. The statistical techniques employed are the probability density function, the autocorrelation function, the power spectral density, and the crosscorrelation function. The results of these techniques are discussed in general terms and related to turbulent flow parameters. The analytical process, including the digitizing of analog data, was verified using known functions. The analysis of constant temperature anemometer data from screen and cylinder turbulence generators matched results previously reported. The program was developed to support the investigation of flow/laser interactions. The program is not limited to fluid analysis. (Modified author abstract)
