Experimental Method for Pressure-Velocity Correlation Measurements in Three-Dimensional Turbulent Boundary Layers

  • L. Paulsen

An experimental method is proposed to investigate the lateral correlations of pressure and velocity within a three-dimensional turbulent boundary layer. The measurements are performed by a pressure-velocity correlation probe, consisting of two pairs of closely side by side mounted miniature hot-wire probes and 1/8″-microphones. The distance between the pairs is variable. That allows to analyse as well space correlations perpendicular to the stream line as time correlations. The data processing is done by a digital computer. Thus all correlations and spectra are calculated from one ensemble. By means of digital filter procedures a distinct analysis of micro-scale and macro-scale characteristics is possible.
