A multipoint detection method to identify coherent temperature fronts in a turbulent boundary layer over a rough surface
Abstract
A conditional technique, based on the detection of temperature fronts at several points in the spanwise direction in a turbulent boundary layer, is developed and compared wiith a one point technique (VITA) and a method based on the visual detection of fronts. The multipoint approach represents an improvement over the one point technique. Conditional averages of temperature obtained with both techniques, are presented.
