Summary
MEASUREMENTS OF THE LONGITUDINAL VELOCITY FLUCTUATION AND OF THE TEMPERATURE FLUCTUATION IN A TURBULENT BOUNDARY LAYER INDICATE A STRONG CORRELATION BETWEEN VELOCITY FLUCTUATION AND TEMPERATURE FLUCTUATION IN THE IMMEDIATE VICINITY OF THE WALL, THE ABSOLUTE VALUE OF THE CORRELATION COEFFICIENT APPROACHING UNITY AT THE WALL. THE IMPORTANCE OF LOW-SPEED OR HIGH-TEMPERATURE STREAKS IS EXAMINED AND QUANTIFIED BY CONSIDERING JOINT PROBABILITY AND SPECTRAL DENSITY FUNCTIONS OF VELOCITY FLUCTUATION AND TEMPERATURE FLUCTUATION.
